I'd forgotten about the Speed thing!  He is in fact on 13.<br/><br/>The Key works such that it'll 'open'<em>any</em>door with a lock mechanism to Malfeas.  Right now, there's three quarters of an intact door leaning against the wall (it was fully intact before Shenanigans), and aside from the stone doubles that Sondok made for her entrance (which don't themselves have a lock/key mechanism), there's not been a single other door in the complex.<br/><br/>Would have messed with the geomancy, after all.
