I'm running a games day and for the Inquisitor section I'm doing the running man. (Yeah like the movie!) I have a 4 2 * 4 Tables to be laid out like so... |-|| if ya know what I mean.

I have tonnes of terrain and crates etc but I need some rules for creatures that will be roaming the arena. I'm using 40k & WFB creatures like Zombie Dragon, Hounds, Dragon, Balrog, Nazgul, stegadon etc...

Should I use their normal rules or make some special inq rules up?
