Fourth Age

The Fourth Age is also known as the Age of Mortals. During this time the surviving races began to rebuild and flourish amongst the world. Heroes from this age include Arrav and Camorra, both of whom have a statue in the Heroes' Guild.

Humans
Aside from a few settlements in the Kharidian Desert and the refugee town of Burgh De Rott (Meiyerditch, although being the largest city with human population at that time, was already ruled by Vampyres by then), most humans in the beginning of the 4th age had abandoned civilisation due to destroyed settlements and lived in barbaric tribes. The major exception to this was the city of Saranthium, but this was eventually wiped out. As the age progressed, they started to build new and permanent settlements, some of which turned into mighty cities by the late Fourth Age, thus allowing humans to become the dominant race in Gielinor by the end of the Fourth Age. Humans would not have become dominant, however, if it were not for the discovery of Rune Essence.

Gnomes
Gnomes returned to the surface right after the end of the God Wars, where they found their settlements destroyed. Between the 3rd and 5th centuries of the Fourth Age, gnomes were forced to hide from barbaric human tribes, preventing them from extinction. Shortly after that, the Grand Tree was planted and gnome civilisation and technology began to thrive.

Dwarves
Dwarves remained under the surface during the Fourth Age. During that time, they discovered a huge cavern where they built Keldagrim. After the city's foundation, most of their magical powers were somehow lost, allowing them to only cast Superheat Item. During the rule of King Alvis, the Consortium, which quickly became a ruling organisation in Keldagrim, was founded; by around the year 1650, after King Alvis's death, the Consortium ruled the Dwarven Realm entirely. Due to their lack of magical abilities, the technology of dwarves had become very advanced by that time.

Elves
Elves did not remain enclosed in Tirannwn during the Fourth Age; they ruled large areas of modern day Kandarin for at least part of the age, there they taught humans and lived peacefully. This continued until the Iorwerth Clan, who worshipped Zamorak, took over Prifddinas during the Battle of Prifddinas. Rebel clans were forced to stay in Isafdar, a forest south of Prifddinas.

Goblins
When the Fourth Age began, many of the goblin tribes fought against the other races for resources. By the midpoint of the Fourth Age, goblins were losing the competition for resources and started to fight amongst themselves, culminating in the Battle of Plain of Mud. Throughout the Fourth Age, the majority of goblins became weaker and less intelligent, until they became only a minor threat to other races. Cave goblins were an exception to this as they remained underground, cut off from other civilisations. Still, eventually, near the end of the Fourth Age, some of the goblin tribes started to build small permanent settlements like the Goblin Village.

TzHaar
TzHaar, living an isolated life since the First Age, make the first documented contact with the surface people. The TzHaar civilisation considered humans as pets during this time.

Vampyres
Under the rule of Lord Drakan, the Vampyres had taken all of Morytania and enslaved the population. The lands to the east of what was once Hallowvale became known as the Sanguinesti region, and this is believed to be where the vampyre populous lives. The Vampyres have less power the further they stray from this region, so more outlying settlements are generally less ruined and downtrodden, those living north of the Mort Myre Swamp are relatively free to manage their own affairs, however those in the Sanguinesti Region are treated like cattle and routinely drained of blood. All people in what is now known as Morytania pay Blood tithes to the Vampyres. Eventually, Lord Drakan felt strong enough to attack Misthalin, but he was defeated and the River Salve blessed against him. By the late Fourth Age, Morytania was little more than a legend, and people began to settle in the North. They all became enslaved.

1st to 8th centuries

 * 1?:Gnomes return to the surface after hiding underground during the God Wars, although the dwarves were unaware of the end of the wars until millennia later.
 * Right after the beginning of the 4th age, the Fist of Guthix was created.
 * 1-200: The druids, worshippers of Guthix, built stone circles to worship Guthix during this time.
 * 31-60: The first star chart that is not destroyed was made in this time period, believed to have been made by the great astronomer Scorpius.
 * 200-500 approx: Barbaric humans hunted the gnomes to near-extinction, causing them to retreat to hidden settlements.
 * 600-900: Permanent settlements at Entrana, Falador, and across Karamja are constructed.
 * 700: Avarrocka, later known as Varrock was built. Varrock is the oldest surviving human settlement outside the Kharidian Desert in the world today. It was founded when a tribe found a baby abandoned, and took it as a good omen. The baby eventually became Arrav, a famous hero.
 * 750-850: The people of Avarrocka became very powerful, and conquered their neighbouring tribes, eventually forming the first human nation, Misthalin. Misthalin in the mid-Fourth Age, however, was little more than a rough conglomeration of tribes, all of whom paid homage to Avarrocka. Nothing that modern scholars would call a nation existed until the end of the Fourth Age.

9th to 15th centuries

 * 800-1000: The kingdom of Asgarnia was founded in this time.
 * 900-1000 approx: The government of Avarrocka changed to a monarchy during this period, but the precise date is unknown. It may have been the creation of the Monarchy when the city was renamed Varrock, but it could also have been the start of the Fifth Age or the "official" founding of Misthalin.
 * ??69: After large human settlements were able to defend themselves, the Battle of Plain of Mud takes place between goblin tribes. It is believed that this took place in the middle of the Age, probably between 869 and 1269.
 * 1100: Robert the Strong supposedly forces the Dragonkin race into either extinction or remote location.
 * 1100-1200: Many dark creatures from Morytania attacked Misthalin, especially Avarrocka. Seven priestly warriors defeated them and blessed the River Salve, making it impassable to creatures of Zamorak.

16th to 20th centuries

 * 1500-1700: "Old Asgarnia" was presumably destroyed in this time, and Falador was laid to ruin. It is unknown exactly how this happened, but as records show Falador was founded in year 7 of the Fifth Age, while also stating it's existence in the mid Fourth Age, historians have deduced that the city was destroyed in approximately this time period.
 * 1650 approx: After the death of King Alvis the consortium takes over Keldagrim. During the next few hundred years the dwarves became very prosperous and wealthy, as well as technologically advanced. The consortium's leadership enabled the development of steam powered boats and trains, and advanced methods of smelting ore in factories.
 * 1769: The Bonde Farm Massacre occurs.
 * 1777: Settlers came up the River Salve, looking for places to settle. They did not heed the warnings they received at Paterdomus and settled in Morytania, building Canifis, Port Phasmatys, and Fenkenstrain's Castle. They all eventually came under the dominion of the Vampyres. Port Phasmatys was eventually freed, but they were betrayed by their saviour, Necrovarus, and became ghosts enslaved by him.
 * 1800-150 of the Fifth Age (date unsure): The gnomes eventually re-established contact with now more civilised humans.
 * 1930: Elves in modern-day Kandarin found the Arandar mountain pass abandoned and inaccessible. They sent 5 scouts under the mountains. The only to return was Adwr, who brought tales of the Iorwerth Clan's rebellion. King Baxtorian ordered the Elves return to Tirannwn to retake Prifddinas. They failed, and King Baxtorian returned to find his Kingdom in ruins and his wife dead. It is said that he was so sad he buried himself under a waterfall.
 * 1937: The town of Lumbridge was founded in Misthalin. The first Duke of Lumbridge is believed to have been named Polonius, and the town was commissioned by King Claudius. Al Kharid was built soon after, but it's people were independent of Misthalin.
 * 1967:The town of Ardougne sends forth an army to fight the great Battle against a group of Zamorakians living in an Outpost to the North-west. Very heavy casualties ensue, and after the battle, a truce is agreed. One survivor goes on to become the first King of the Ardignas line (and, some say, officially founded Kandarin); the other founds the Ardougne Market
 * 2000: Discovery of Rune essence, leading to the dominance of humans.

Events with unknown dates

 * Unknown: The city of Avarrocka launched a crusade to a Zamorakian temple in the desert. Records have been lost, so the reason for this is unknown.
 * Unknown: Avarrocka was renamed Varrock, presumably to celebrate a historic event.
 * Unknown (early part of the age): The Elven King Baxtorian, leader of the Cadarn Clan, the most military of the clans, lead settlers over the Arandar mountains.
 * Unknown (Mid part of the age): The dragon Garak, who had destroyed many villages near the Wilderness, was slain by the hero Camorra.
 * Mort'ton is affected by the haze originating from Castle Drakan, turning inhabitants into Afflicted and disturbing shades in their catacombs. This, according to the Diary of Herbi Flax, happened when Avarrocka had been renamed Varrock.
