If anyone has access to a scanner and the Illithiad, there are many cool - and different - images of the illithids in that book; Gary Gygax created them (originally called "Mind Flayers") as a tribute to H.P. Lovecraft, or so I've heard. Essentially, they're 6-7' tall humanoid amphibbeans (sp?) with a beaked mouth surrounded by four (or six for the larger Ulitharid variety) 4' long tentacles, and large, bulbous white eyes that see only in the infrared spectrum. They also, IIRC, only have three fingers and a thumb, and generally have gaunt bodies. It would be darned cool to have one of those buggers running around, terrorizing Posette (and mind-blasting Victoria back to the previous millenium... :-)). Beholders are fun critters too - and according to the defunct Spelljammer setting, they come in so many shapes and sizes that just about anything roundish with a mouth somewhere, a large eye, and at least three eye-stalks can be called a Beholder.
