Oliver and Ryder were actually a joint effort between my friend and I; we had this idea to make up OCs that would tick all the boxes of what the other person likes in a character! I made Ryder with her in mind, and she made Oliver with me in mind. We decided pretty quickly that they were brothers, and bits and pieces of the "lore" fell into place over time. Because they're pretty much just eye candy and wish fulfillment OCs, they don't have a lot of development, but I still like them a lot LOL.
