I don't really know where to even find a pic for Warren. -_- All I've got on my computer are a few pics from FF7, Trigun, and KH. It'd take days to search for anything remotely suitable on DeviantART or something.
Not terribly sure where to go for a rep for Tyrla either- most of the tiefling pics I'm finding are 4e tieflings with large/prominent horns (or similar defects). Any ideas?
I can't find the first picture that came to my mind, but I immediately thought that a picture with a black cloak might work. I wasn't able to find many that I thought fit though...
Eh, may as well go with that first pic from the Tome of Battle.
It's probably the closest thing to a pic of Warren that we'll find. Since Geocities doesn't allow me to host an image on my webpage and post it on forums or whatnot (as I found last time I tried to post a map for another game), I can't really post my resized copy of that image. So use whatever you're hosting that image on or something.
