Thelestes

Thelestes embodies murder and death, wielding powers far beyond those of her sister succubi. She came to Eberron twenty thousand years ago, fleeing a bitter feud with the ultraloth lords of Mabar, and once the rajahs are freed she intends to wreak her vengeance on the realm of darkness. Her first loyalty is to Kashtarhak, but Thelestes might lend her skills  to the schemes of any of the councilors. She also maintains identities in House Phiarlan, House Thuranni, and many smaller crime guilds, as she takes pleasure in watching mortal corruption and death. While she usually eliminates her targets with a deathblow from a small weapon, she possess great skill with the spiked chain and turns to using that vicious weapon in an extended combat.
