Yando came from a poor family on the aqualish planet of Ando, when he was a teen he joined a Hutt cartel offworld so that he may provide for his family, becoming the Hutt's personal boxer, the little money he made off these fights (as most went to the hutt) was sent back to his family in Ando, but Yando was arrested by the imperials for being in a cartel and participating in gang activity, he was jailed for years and as he wasn't fighting he wasn't earning money to send back to his family and they had become slaves to the imperial war machine, working in hopes of food and shelter. Yando eventually got out, too late though as most of his family has been killed by the imperials directly or their bodies gave out due to the back breaking work they had to endure for years on end.
