When he was young he was an adventurer wanting to find and discover new lands. When he got to Shartak he wanted to found a new settlement, but was captured by natives. He and his fellow adventurers were slaves of the natives doing the hard labor. The natives killed outsiders who did not please them or work hard enough. Before long he was alone and the natives adopted him as one of their own. They taught him the native language and writing, then before long he forgot his former life as an adventurer.
