Sonas is good-natured, merry and trusting, quite alike the stereotype people have of halflings. Though Sonas might have it maybe even more exaggerated. He does not fight for the glory or the kill, more he fights to protect and to free. He doesn't boast of his kills or assistance, he knows it always is a group's effort.
Having never been a servant to others, but grew up in freedom among the Varisian traders, who actually were given him in Korvosa by his mother when he was just born. The group acepted him as one of their own, especially because having a halfling more along would be considered lucky. They were heading a caravan down the Dawn Shadow Path towards Kaer Maga. During this time Sonas grew up, listening to the joy and hardship that befell the caravan, music and song, teamwork and struggle. Eventually he was given his name at the age of two as his adoptive parents wanted a fitting name for him. He began to hum and softly sing as the music seemed to start at nights when the violins came out and the dancing began. Laughter and joy seemed to radiate within the little halfling boy as well as among the caravan travellers. They called him Sonas, referencing to the Varisian word for sound, indeed a fitting name.
Eventually the caravan made their way to the Cinder Road, travelling up and down the road from Wartle to Riddleport. There were dangers there as well, more giants, more goblins, but even so, through comradery the caravan survived. Sonas learned to contribute at an early age, helping others first before seeking shelter himself when the caravan was under attack or when storms were blowing overhead. It was no wonder that Sonas became a paladin in service to Shelyn, protecting the wonder of song and music. Halflings were considered a good luck charm, but none more so as Sonas himself. When he was around, accidents along the way tended to have less disastrous consequences. Someone was able to barely jump aside from a sudden mudslide before he got carried away. A sick person miraculously didn't get worse from a serious disease.
Though he has loved the years of travel and belonging to a group and family, something tugs at him now they were getting close to Wartle again. Perhaps the news coming from Sandpoint about the cathedral being completed, the option of hearing other people perform or the need for protection for travellers there. To Sonas, it seemed like perhaps it was now time to leave the caravan, to help others. Truth be told, the caravan did grow since he grew up, so they might not miss him that much.
