Gibby is a weird..? creature? to look at, he seems like he is in a constant state of regeneration and erasing himself from existence similar to a chemical spill.
Purple harmless smoke that leaves his body is noticeable to those around him, though prolonged exposure is bound to make you a little more.. wild.
Wearing just travellers clothes and no visible weapons, you might think of him as a mad man trying to be an adventurer, but he will tell you.. something.. once he thinks of something clever. Just give him a chance c:
