Edgeville Dungeon

Introduction
The Edgeville Dungeon is the only dungeon in RuneScape that begins with a normal area and turns to Wilderness partway. It goes to about level 5 Wilderness, so other players can attack you when you're in the dungeon. None of it is multi-combat flagged, though, so you can't be attacked while training at least. Still, any who wish to explore the deeper parts of this dungeon had better be careful.

Entrances
There are two entrances to the dungeon. One is in, as one would suspect, Edgeville in the ruined house south of the bank. It is marked by a mark on your minimap.

Another entrance is north-west of the Cooks' Guild near Varrock on the east side of the River Lum. It's useful to players who wish to collect big bones, since it leads right down to a group of hill giants and is fairly close to the Varrock bank. To get in, the player must bring a brass key which can be found in the dungeon.

Non-wilderness area

 * There is a Mining spot inside the dungeon with 2 copper, 2 tin, 3 iron, 3 silver, 6 coal, 1 mithril, and 2 adamant rocks.
 * Quite a few Hill giants live in the southern-most area of the dungeon. They are a popular place to collect big bones, since those with a brass key can take a short cut to and from the Varrock bank.
 * Players with 51 Agility can squeeze through a pipe on the east side of the dungeon that leads right to the Moss giants in the Varrock Sewers. It can be used in either direction.

Wilderness area

 * Several Chaos druids in the wilderness section, well known for their high drop rate for herbs.
 * There are quite a few red spider eggs respawns in this dungeon, making it easier to collect them for potions.
 * Several Black Demons live farther inside the dungeon, yet closer to a bank than most others.
 * There is a demon who resides in the dungeon named Chronozon. He's a critical part of the Family Crest quest and can only be killed after successfully casting all four of the elemental "blast" spells on him.
 * The Earth Obelisk is in the dungeon near Chronozon, and the Air Obelisk can be accessed through the dungeon as well, past the Black Demons.
 * The dungeon is the only location to house Earth Warriors. You need 15 Agility to get to them.
