The quest ID is "1", so this internal test quest has been in the game files since the beginning. Originally (or at least as close to "originally" I could find), the quest was:
Find the forgotten location and cast the magical spell.
2x Shade of Akama
Alexander may refer to Alex Afrasiabi (Lead World Designer since 2008), who at the time was a quest designer for Blizzard. Also, I'm reasonably certain that that NPC ID linked to a different NPC prior to The Burning Crusade. Blizzard has a history of repurposing IDs, though not done often.
