I have a LE Paladin of Tiamat (Vengeance) named Taevyn Blackwyrm (my main S1 character). She is ill-tempered, forceful and demanding and has a vendetta against the Cult of the Dragon. She sees herself as the Talon of Tiamat - an inquisitor; whose role is to weed out corruption within the church of Tiamat and excise the wound (kill them), clean out the puss (their supporters), so that the dragon may grow stronger. She made it very clear on numerous occasions that it was by the Grace of Tiamat that they were spared (as she acted on behalf of her goddess to save numerous peoples).
She is convinced that the Cult of the Dragon has manipulated Tiamat, and seeks to do her harm in some fashion and is on a quest to find evidence of her beliefs. She does not believe they have suddenly changed their tune, and holds a massive grudge against them for having corrupted the Dark Queens children for centuries and transforming them into undead abominations (Dracoliches).
Ironically, she has a competitive rivalry with a LG Paladin of Bahamut. They compete with each other to prove which is the better Dragon deity, and which of the two are superior. They don't actually seem to hate each other however, it comes across more like a sports rivalry than anything.
