Reading a bit of middle East history, Crusades era. Shawar was a former ruler of Egypt, when under imminent attack - which for him was all the time - had planned to burn the city down and everything in it, stocking up on tens of thousands of pots of pyrotechnics, possibly an inspiration for Aerys. Quick search I couldn't find any reference on here. http://en.m.wikipedia.org/wiki/Shawar He was eventually succeeded by Saladin, TPTWP? ;)
