Tessel is good-natured, transparent, a bit blunt, curious, and braver than she realizes. After a stint with a mercenary company that proved a very poor match for her, she signed up with the Pathfinder Society in the aftermath of the Fleshfiend Siege.
Background:
Tessel was born as a fourth child (a latecomer) to a well-off merchant family in a small Qadiran city. With three siblings before her (and quite some years between her and the third), there was not really a role for her in the family: Her eldest brother was to take over the family business, her sister was to take over the household, and her youngerst brother was sent to the church of Sarenrae. Following her heart, Tessel also studied at the temple for a few years. However, she could never compare with the grace and charisma of her brother. The priest that tutored both of them was closed-minded and sent her away to find a different purpose in life.
Not really knowing what to do but without any strong ties to keep her at home, Tessel signed up with the mercenary band of Korshal One-Eye after she learned that they could use a medic. She was with his company for a few months, without much satisfaction. He expected everyone to fight, and she didn't feel much cameraderie among the group. Her breaking point was hit when the group found itself in Absalom during the Fiendflesh Siege. In this moment of distress, Tessel felt that the group could finally accomplish something worthwhile. However, Korshal wasn't interested in fighting the invaders. Instead, he hired the band off to one of Absalom's noble famities to increase the guard of their mansion.
Thoroughly disappointed and disgusted with her leader's choices, Tessel quit the next morning. She was now stranded in Absalom, and again looking for direction in life. Inspired by the Pathfinder Society's actions in repelling the invasion, she decided to join the Society. She's flourished under the training of the Master of Blades, and has even regained some energy to pick up on the teachings of Sarenrae again, learning that her intentions and honesty are more important that the grace of her dance with the scimitar.
