Delar bought a ghostly blade from the weapons shop in the Haunted Woods, but in his first battle with it, he found that it went out of control and tried to attack the crowd, with Delar unable to let go. His friend, Jan, managed to stop him, and Delar tricked a mean Grarrl into buying it off him under the impression it would make the bully stronger.
From the picture with the story, it seems like Delar is a red Techo. He appeared in issue #13.
