This specific Illithid has dark grey-violet skin, in sharp contrast to many of its fellows. It also has an extra mouth tentacle, slightly longer than the others, that appears to end in a thick "spike", as if the skin solidifed somehow and formed a jabbing horn. Other than that, it appears to be dressed much like any other Illithid. It weilds powerful psionic blasts and is able to cat itself in secreted acid to affect attackers. A well infrmed Illithid hunter might surmise that it is a high ranking illithid, perhaps one entrusted with serving the Overmind directly in some capacity.
