Apprentice Argoly was an apprentice under Ansirem Runeweaver. After being swiftly trained by Archmage Ataeric, he was sent to Runeweaver as an apprentice. When Runeweaver gave him the task to gather some fresh Alterac grass still growing outside the walls of the floating Dalaran island (to be used as an additive to tea), he apparently took out some Felweed from a folded pouch he kept with him and started chewing it before going about his work.
The recreational effects of the Felweed were enough to impair him, so that he ended up going over the edge of the island and plunged to his death in Crystalsong Forest. His remains were found later.
