I will use the basic Tav, but otherwise I have "prepared" two different ideas, depending on my mood when I can finally play:
An older human Researcher who made a Pact with an Archfey, to gain more knowledge. While not exactly open with things he himself knows, he tends to be a rather helpful and nice person. He tries to evade violence, since he does not really feel at home on a battlefield. He is rather interested in Karlach to ...protect him.
The other character is also an aging human Pactmage. But he made the pact for magical abilities that help him in his completely legitimate business. He ..finds lost items and sells them for a finders fee, but many claim he is just a criminal. While he loathes to break his word and acts generally friendly and affable, he is not really a good person. As long as hi did not give his word, he will backstab persons if he sees a benefit - and sometimes just to seduce someone he becomes interested in. He is also rather careful, maybe even cowardly, and evades risks if possible.
