Arya thinks Unigons are the hybrid offspring of Unicorns and Dragons. See her drawing here.
Well, I beg to differ. A Unigon is simply a polygon with one side. (see duogon, trigon, quadrigon, pentagon, etc)
Here’s an actual picture of a Unigon.
See anything? Good.
Unigons don’t exist.
At least that’s one thing Arya and I agree on.
