A bit more down to earth than most Bioware PCs, I've played with in the past. He wasn't an evil man, but it when came to impressing Morrigan, he betrayed the Dalish elves. He preserved the Anvil of the Void. He killed Wynne. He sided with a Lothering merchant. And he destroyed the Urn of Sacred Ashes all in an effort to please Morrigan. But the Witch of the Wilds, wasn't enough for him, he wanted Leliana too...He was crazy about both of them but when push came to shove, he ultimately chose Leliana because he had a feeling that Morrigan would leave him in the end. So he decided to leave her first.
So what kind of attitude does your Grey Warden have?
