Wilderlands Age of Worms
High Elf Rogue
Tirra is a member of the Champions of Tula, whose arrival in Rastingdrung motivated the party to initiate their adventuring careers. The party intentionally avoided interacting with the other two Champions (Auric and Khellek), but Random played a few games of knife tossing with Tirra at the Feral Dog before discovering her identity.
I can guarantee that the party will encounter the Champions of Tula again. The only question will be if they will remember Tirra by the time that happens in the game. They’ve probably forgotten her already.
The party would encounter the Tirra and her friends again at the Champions Games in Tula, although at that point Tirra had retired from the gladiator team (“bad for business”), replaced by Khellek’s flesh golems.
