Sad Rock has grown a lot during his years of training with the Pathfinders. He is not only completely incompetent with his club, only mostly so.
Some of his natural gifts have been strengthened, but his personal interactions still need work. He has grown strong, but still does not tender the interactions with others well. He can hunt and climb, but shows no interest in social situations. He is very eager to learn and do well, wise enough to realize that he has much to learn.
At his 'core', Sad Rock has a sweet and gentle heart, but since he is both shy and awkward around others, he often has a hard time expressing that kindness. It does not help that he is of somewhat unusual race, differing from many of the others.
Sad Rock understands the mission and motivations of the Society, but still tries to make friends and do right by the world. He sometimes wishes the Society had a greater role in Absalom beyond the pointless collection of history. He wishes the Society would do some good in Golarion for the betterment of all.
These people are lost. If I could get them to listen to me, we could make the world a better place.
Sad Rock loosely supports the Silver Crusade as it is the closest fit to what he truly believes.
