Uthacalthing-Tymbrimi.

The tymbrimi are humanoid in shape and anatomy.

They have two features that make them distinct among the Galactics: their adaptation hormones and their corona.

The corona is a set of tentacular threads emitting from the head upward, it is a probability organ fitted to construct emotional glyphs that convey a specific emotion.

These glyphs then can take on a mind of their own, in a sense, as certain ones are used for everything from scouting other creatures in the dark to trying to implant a thought in someone else's mind.

The adaptation hormones are a special ability they have ; under physical stress, the body releases a flood of hormones to the parts of the body, causing the stress and alters them.

It can make skin thicker, nails harder and longer, widen the nostrils for better air intake, change the placements of nerve endings and body part placements, etc.

Also, the tymbrimi feature a rather unusual quality among galactics ; they are tricksters.

They play practical jokes on each other as a part of their civilization, and have an extraordinary sense of humor, much like humans but 100-fold stronger.
