Zandar Horfyre

Zandar Horfyre is a dark wizard found on the top floor of the Dark Wizards' Tower, west of Falador. The fastest way to get there is by taking the Agility shortcut over the crumbling wall by the west Falador bank, and heading south-west until you find the tower.

You need to talk to him during the quest Fairytale I - Growing Pains, as he is a friend of Fairy Nuff. He will take the symptom list you are given during the quest, and suggest you speak to Malignius Mortifer.

Talking to him and refusing to leave will result in the player being teleported to the Lumbridge Swamp.
