Google didn't help and neither did searching this site. I know the prefix "dun" means dark, and I was curious about the name of a character from a video game I love to death, Dunban. Closest is Duncan, which means "dark battle" according to this site and that really fits the character. Yet I'm still curious if there's a chance the developers didn't just name him Duncan with one letter changed. The game in question is a JRPG so I'm thinking the suffix may be Japanese but again I found nothing by searching.
