How easy is it to move between areas/levels? It's a siege so I imagine a certain degree of chaos, but beyond the Room of Seals (tm) is there anywhere that people who aren't assigned there would struggle to enter?

Also, for Keep Folk, where are the sleeping arrangements like? Is everyone just in the barracks, in like one big (or several big) rooms with roughly constructed beds? Or do the entourages have their own separate areas?

Edit: Also... how big is 'gargantuan' Irenia. Wrathion has flung himself at dragons bigger than him before so I cannot rule this out, much to everyone's dismay.
