Tel Branora is the Telvanni stronghold of the sorceress Therana. The tower is somewhat away from the port where one arrives by boat. The tower is being staked out by a lesser Telvanni mage and a sub-quest can be attained by Therana's captain of the guards to dispose of these unwelcome guests. Therana herself is somewhat unstable (as even her mouth in Sadrith Mora will attest) and is best approached with extreme caution.
