Awww man...
There have been a number of deaths that have been announced from time to time here on the forums about artists and authors in the RPG biz.
To be perfectly honest, all of those previous announcements - while certainly sad - never struck home or bummed me out like this one.
This counts large. Keith Parkinson created a vision of AD&D and DragonLance which our artists at DLA worked three years to emulate. His work on Draconians ("What do you mean we're lost?") is the classic reference art. I have it on my wall and look at it often.
My condolences to his family and friends who knew him; simply knowing of him, his contributions as an artist will live on.
