In the first adventure of the Iron Kingdoms Witchfire trilogy Alexia practices necromancy openly on a very large scale. It always struck me as odd that the organization tasked with investigating black magic, the Order of Illumination, did not investigate this enourmous incident. So in my campaign the Order does indeed send out a senior agent to investigate.
Fittingly Privateer Press just recently released a great mini of just such an agent, an “Illuminated One” – Glyn Cormier. And while the whole incident with Alexia would be before her time in official Iron Kingdoms canon, in our campaign she is front and center to give Alexia a bad time.
