Bound to and weilds Asheia, one of the seven swords. Asheia’s element is fire, which strongly compliments Tirana’s spell list. Already a powerful sorceress, this sword greatly aided her physical fighting prowess. Her (former) base is just a few miles northeast of Gotham.
Peter, Sexy, and Kyra attacked just as she bound to the sword. Peter had defeated a group of her (then) thugs of the Splitstreet Gang. Peter was the reason she didn’t kill the whole party. Kyra barely escaped, with a combination of a haste, darkness, and levitation spells, since Peter wasn’t able to teleport her to safety.
After the excursion to Hatlminster (immediately after the party’s excursion into Tirana’s base and stealing the book as well as her entire library), Tiranna’s base seems to have been completely cleared out.
Tiranna also attacked the Didela tower in Gotham, destroying a lot and killing a few. Then she fled. There is a task force in search of her, but details are confidential.
