Digging the intro flavor. Would this be compatible with the Planescape setting? Been toying with how to adapt BitD to the plane-hopping, faction-centric, mind-bending intrigue and action
Hopefully you have already purchased this, but there is another FitD game that might be relevant. Sig, City of Blades, a city based game (so, not so much plane hoping) but the city is very much inspired by Sigil.
