Omniana was created and written by Aaron Delamatre​. After graduating from the Art Academy of Cincinnati in 2002, he ran a small theater company, The Art & Drama Club, for which he wrote and directed plays that used puppets and actors to tell fantastical stories. He has written and illustrated comics for print and online, including Dungeon Face, which crowd-sourced an improvised story by having readers vote on the protagonist's decisions. He has also had numerous exhibitions of drawings, paintings, and sculptures. By day, Aaron works as the preparator for the Carl Solway Gallery.
