This particular Igor made a rare error among Igors, and let himself be connived into taking part of one of his marthter's experiments. As might be expected by the laws of narrative, the experiment went rather awry, and even the Igor from the next castle over had trouble putting this one back together.

Igor now keeps away from inventors, wizards, "scientists", and others who might remind him of his shame. He finds an odd comfort among the mad beggars of Misbegot Bridge, and helps keep them alive when the world treats them even more poorly than usual.
