I got a tactician named Pohem and have no idea who he is. He doesn't show up in the Roster section. I received him from a battle way before Crom became King. At first I thought it was a glitch and I got one of my future kids early but he isn't. Then I thought maybe I somehow accidently got one of the DLC characters from the past Emblem games, but again he isn't one of them either. I looked up all the characters you can get in the game and his name does not show up anywhere. He also doesn't have any dialog with anyone either.
