Ok, first off, man do my maps look ghetto. If anyone has a decent program for map creation, I'm all ears.
Currently, Marcus and Shryke are just under the secret cage. Pyrrhus is at its entrance. The three just to the NW of the yellow cage are the now loose mantids.
There are some engaged in combat with beasts and some running.
Porthal is in one of the cage entrance ramps while
Ingron and the
Ogryn flee down the catwalk towards the stairs that go up and out towards the Circus Entrance. The other set of stairs on the left of the catwalk join the catwalk to the floor level with the cages.
Excuse the haste, Halloween and all

Please hit me with any questions and feel free to post actions. I'm sure I've missed more than one detail. The width of each individual us approx 1 meter for reference. It seems possible to simply seal yourself in the secret cage to avoid the worst of the pandemonium. That is, unless your name is Gideon & Aria.
