I think the guild should be moved under Knothold Glade, and the entrance is outside the gates, where that werid looking shed is, I'll eleberate:
The Hero walked into the map room, to be greeted by a crowd congraculating him on destroying Jack Of Blades, But Jack's Minions ruin the celebration, taking the Hero off guards, decapitating him, killing him. The Guilds apprentices and Heros easilly destroyed the Minions, but felt it was no longer safe, so all thier combined power they teleported the guild under knothold glade, (By the way this happend just after Jack was killed). From then on the buit tunnels and passageways.
What you all think, eh?
Oh and, I know this is Off-Topic but I thought I'ld bring it up; The new main boss could be a load of Minions that have learnt to fuse together, along with the summoners, so the boss is: A giant summoner, Big as an ice troll, fast as a minion, powerfull as a summoner, with the ablity to summon undead and minions...
