This poor guy lives under not very ideal conditions (indoors, low light), but has been happy and doing his thing for about 5 or 6 years. All of sudden he's started to dry out at the bottom, and is withering very quickly. I don't think it's a case of over or underwatering, but anything is possible. I would be very grateful for any advice.

Cannot tell much from the pix other than its a columnar Euphorbia. It seems to have a fungal rot and cannot be saved. Fungal rot attacks the plant from the inside out and the plant is usually too far gone by the time one sees symptoms on the outside. The plant probably has been declining for years.
i don't know if the problem is fungal or not (probably is, though). if you can determine if it IS fungal, you could try treating with a fungicide. you could also try cutting off the diseased part and re-rooting it.
It seems to have started at the bottom and is traveling up the succulent VERY quickly, I can see a visible difference every day. I have a feeling I'm too late, but maybe I will give fungicide a try. Is there any way to test for rot/fungus/etc?
I think I'd go with cutting off the top, maybe 7" or so and then try rooting it, although this time of year is the not the best. If the cut end of the top looks like there is any fungus, or rot, even a little bit, I'd throw the cactus out. http://www.turtlestuff.com/growingcactus.html
