My current one originates from flight rising. I fancied something I hadn't used before and when thinking of dragony/medieval themes the name Pendragon came up.
As you can imagine that was already taken, so then I thought more along the lines of Olive Penderghast from the movie easy A, then swapped out the ghast for an expression similar to how I describe the flavour of some foods, that matched how pleased I was to start the game

Penderghasm is a bit more unique and a bit more of what I was going for, then when I started going by it here I kept the stars and squiggles from my previous username.
