Cleon
Legend
A dessicated spider-like creature with withered fur and empty eye cavities filled with phantom lights in its serpentine head.
Work better for you?
Well neogi are also partially eel-like, and that description makes no mention of its arms.
Also, I doubt fur can be "withered" - it's not a fleshy organ like a leaf or limb. Furthermore, the original description of the Undead Old Master says they are "hairy, brightly-colored" although they fade with age. Clearly, they maintain the Neogi habit of dying their fur in caste/status patterns.
Hmm, since the fur colour is dye I infer that some Old Masters are proud/vain/old-fashioned enough to keep their fur dyed while others just let the colour fade. That suggests we should leave the brightness/fadedness of the fur to the background text and just mention its coloured in patterns in the description.
How about.
A hideous monstrosity resembling a dessicated spider with the neck and head of a withered eyeless eel. A brittle coat of short fur covers its spider-body, colored in elaborate patterns. Two spindly arms fold out from under its eel-neck, ending in clawed hands. The empty eye-sockets in its anguilliform skull are holes filled with phantom lights.
Description: Fur coloured/faded according to taste.
