Archmage Sedridor

Sedridor is the current archmage of the second Wizards' Tower, which trains wizards in the magical arts. He can be found in his office on the second floor of the tower.

He plays a central role in the quest Rune Mysteries by preparing an Icyenic Purge to stop a faulty teleporting beam. He also banned Ariane from the Wizards Tower as shown in the Lore "The Burning Tower." After the quest Rune Memories Sedridor will give players the Archmage title if they have 99 Magic and Runecrafting. Players may also loot his personal rune essence chest after the quest which yields essence equal to your runecrafting level*5.

Historical
Sedridor used to be the head wizard and chief of research at the Wizards' Tower. In the old Rune Mysteries quest Sedridor, having struggled to rediscover the knowledge of runestone creation, which was lost after the destruction of the Tower by Zamorakian mages decades ago, recently succeeded in this task largely due to the efforts of an adventurer who brought him an unidentified air talisman from Lumbridge's Duke Horacio, who knows of Sedridor and his vast lore well enough to send it to him for examination. He is located in the tower's basement. You are required to talk to him twice during the Rune Mysteries quest. After the said quest, you can use him to teleport to the rune essence mine, where you can mine rune or pure essence. He is seldom visited for this, because he is so far away from a bank. Sedridor has conducted extensive research on runes and the secrets of crafting runestones, eventually combining his research with that of Aubury's rune knowledge to unlock the secrets of the Air talisman, thus considerably increasing the Wizards' supply of runes and leading to the opening of a Runecrafting Guild, which is run by a friend of Sedridor's, Wizard Elriss.

Trivia

 * Sedridor has a brother, another wizard who lives a floor down, by the name of Isidor, who, despite interest in portals, is often forgetful, and can teleport players to the Land of Snow.
 * During the icyenic purge in the Rune Mysteries quest, he is on the ground and second floor at the same time.
 * During Rune Mechanics Wizard Shug reveals that it was originally Sedridor's idea to rebuild the Mage Training Arena. It is also revealed that Sedridor is a heavy drinker of Wizard Mind Bombs, having drinking habits Shug compares to a Fremennik. Sedridor originally had the idea to rebuild the arena during one of his binges after one of his apprentices had killed himself using magic, therefore he wanted to make magic training safer.
 * When he was talked to before starting the old version of the Rune Mysteries quest, if you continued through the entire conversation, he would say "Perhaps I will see you later, *insert user name here*", your character would be shocked and ask how he knows your name, replying "Well, I AM the head wizard.", which might have been a reference to Harry Potter.
