"I was born a slave, but live free. The only thing that can catch me now is death itself."
Liam resented his enslavement since his youth. He often sneaked out of his lord's manor at night to cause trouble throughout Westcrown, relishing the chance to cast off the troubles of the world. His adventures were mild but many: Liam learned magic tricks from a witch, archery from playing war games with street-rat children, and various other skills. Most of all, he learned how to share his memories as stories, and spent many a night delighting his fellow slaves with tales of his experiences.
Of course, it was inevitable that Liam would one day be caught. Rather than punishing Liam, who was a relatively hard worker, the lord of the estate mercilessly killed Liam's younger brother Kaleb in front of Liam. Liam still blames himself for Kaleb's death to this day. Liam decided that he would never get caught doing anything ever again, which is of course a ridiculous idea, but Liam decided it nonetheless.
For the most part it worked out. Liam fled Westcrown with very little supplies, unfortunately leaving behind his family. Liam fled to Brevoy, hoping to thrust himself knee-deep in city life yet again. And so he did, where he spent several years developing all of his techniques, along with a healthy heaping of gambling, drinking, and whore-mongering.
His life found meaning during a trip to the River Kingdoms, where several abolitionist movements call home. Liam, incredibly drunk off of cheap wine and filled with valor, immediately signed up to help. For a few years, Liam felt he had a purpose as his party raided slaving caravans and helped escaped slaves find new lives in the Kingdoms and in Andoran. But, one day, his party decided to go to Cheliax, and Liam felt fear once more. He fled in the night, filled with self-loathing and despair.
When Liam, who was suffering from potent melancholy at this time, heard of the new colonization project, Liam felt a fire spark within him that had been dead since that night he ran away. He signed up, hoping to create a refuge for escaped slaves. It doesn't hurt, of course, that he thinks it would also make an excellent story.
