NPCs are Non Player Characters in RPG (Role Playing Game) vernacular. These guys were done for an issue of The Black Seal that isn’t out yet. Adam went and became a father and got another editor position and became a complete slacker.
(I kid Adam. We won’t go into the projects I’ve been in the middle of for years (and years) now myself.)
These are recent scans from my sketchbook. The final illustrations have been photoshopped a bit. You’ll have to wait until The Black Seal comes out to see what the results look like.
