Even long after he left Paizo, he still felt like a member of that family. His work played such a big part in shaping the character of the setting, it was honestly like he'd never really left. Korvosa alone has his fingerprints all over it. He really brought the place to life.
Always liked seeing him pulling his ninja lurking thing on the forums afterwards.
Rest in Peace, Mike. And condolences to your family and friends, at home and at work.
May you find dragons where you're heading. The cool kind.
