Like most elves of Na-Nal, Selma is haughty, arrogant, and very distasteful of humans. Well, until she found out the plot of the Elven Elder to wipe them all out, then she gains a bit of a conscience and tries to help them out, which led to her getting kicked out of the elven village. She's actually pretty nice, when she's not tossing you in prisons, that is.
As a Water Rune user of Suikoden, Selma has healing, and more importantly, Silent Lake. Backed with her blade, she's a fierce competitor, and any Middle that stands in her way is sure to perish.
