Eberron - Dreams of Xen'drik
Tally was a changeling rogue and a member of the adventuring group known as The Savage Company, led by Jackson Savage. Tally was always quiet and reserved, tagging along behind Jackson wherever he went. She rarely spoke, following Jackson everywhere with eyes downcast, and seemed to be in charge of managing the funds for the Savage Company – whenever the bill comes, Jackson always had Tally pay it.
After Berenessa stole the Dreamstone back from Jackson Savage, it was revealed that Tally was a figment of his imagination, and vanished back into the ether from which she was made. With Jackson’s death, it seems the city has forgotten she existed.
