Lig'Tu was raised in a monastery on the Planet Kurg, the home of the Weren. At the Monastery (whose name, when translated into English, is roughly "the way of the peaceful war") Lig'Tu learned to master the art of Po'Kan, a powerful unarmed combat art that has 3 tenets See the Martial Art spoiler below. After learning all that he could at the monastery, he left Kurg and began to travel the stars, eventually landing a place at the Starlight Fighting Tournament, a perpetual fighting tournament that travels on a vast luxury ship and is broadcast throughout the known galaxies. Lig'Tu's stage name is Anvil, due to an incident in his 2nd professional match that resulted in him hitting someone so hard that they folded backwards in half.
After several years (and twice gaining the championship title) Anvil was approached by some shady individuals who wanted him to throw his next match. "Do it" they said, "or else." Anvil refused, and although he won his next match, the person he was fighting died. While deaths in the ring aren't unheard of, they are rare.
After his match, he headed to his home, where his wife and 12 daughters were supposed to be waiting for him. Instead, the house was locked up, and there was a small box waiting instead. Inside was his oldest daughter's left eye. After considering going after the people who killed his family, he realized that anyone who could take his wife and children would have no problem taking him as well. So, he announced his resignation via a press conference in which he explained what had happened to his family because he had refused to throw a fight. He turned in his title belt, took what money he could get his hands on, and fled (after spending several harrowing days answering all the questions that the authorities could throw at him.
When he was freed, he went to the docks and found the first ship that was leaving port and rented space. This would be the ship that the group will be travelling on. He has rented his quarters for the next decade.
While not a member of the crew, he does interact with them to a fair degree and has come to enjoy their company after a fashion. The only thing that worries him is that every year he gets a package, no matter where they are. and each time it contains the eye of one of his children. He would one day love to get his hands on the person who is sending the packages, and would pay top dollar for 5 minutes alone with the person behind everything.
