Tesni is a dutiful, responsible young wolf. She is very trustworthy and has been given a lot of responsibility even at a young age as she has proven herself able to handle it.
She came to the pack as a pup, young and sick. Her mother had become injured and died so she and her brother had wandered the woods, lost before they stumbled on the pack by luck. Unfortunately her brother never fully recovered his strength and one day when he was playing with the other pups he came too close to the cliffs edge and tumbled over the side. He caught himself on some roots but was still weak and unable to hold himself up long enough for help to arrive.
Tesni was grieved to lose her brother and to this day doesn't speak of it.
