The Prairie Village Campaign: 4e
“This lonely structure is a tall, seven-sided spire of pale green stone that doesn’t match anything else in [ Fallcrest ]. In the days before the Bloodspear War, this was the seat of Fallcrest’s mage’s guild—an order of dozen or so wizards and arcane scholars. Defensive enchantments prevented the orcs from sacking the tower [during the Sack of Fallcrest ], but the guild’s members died fighting for the city or fled to safer lands1.”
