Hi Bastlynn!
Yeah, I guess you refer to Inkoia. I was talking to him the other day, actually he is friend of a friend of mine, and when I saw he was drawing some planescape stuff, we made the connection
I was working years ago for the planewalker site as an illustrator for the Lady's Sharper Eye and some othre stuff, you can see some of my drawings at my gallery in deviantart. My email by that time went by my same name: arcan@planewalker.com
(Unfortunately) I'm not playing D&D anymore, but I like to keep an eye on what's going on in the scene, and I wouldn't mind to draw some more stuff in case you need to.
Cheers!
Iñigo
