From publisher blurb:
The Fire Within is meant to be the first of many supplements for Qalidar: Resistance. Primarily, this one serves to fill out the remaining character levels up to 20 and to introduce some more detailed information on one of the cultures that influence the multiverse of Qalidar. Along the way, we’re also going to expand a bit on the rules for organizations that were outlined in the Basic book. Also, you may notice a few additional abilities listed for ascendants, karcists, and mystics, and a few new pieces of equipment.
Qalidar is a name for the cracks spreading out from a hole in time, and for the pits one drops into when falling through those cracks. Perhaps most famously, it refers to a starless city at the heart of the spiral where three roads named for the three gorgon sisters converge.
