The Evans Clan was founded by Ma' Evans, who sees herself as the spiritual leader of the gang. You first encounter them at <locatiom?> during the <campaign?> campaign.
Ma' escaped from an abusive relationship and joined a group of smugglers. Over time she climbed the ranks and eventually took over the gang, naming it after herself in the process. She sees the gang as a way to provide jobs and stability for "her boys", guiding them like a mother hen to prevent them fighting against each other.
The clan has a single rule: Ma' knows best! – as long as everyone abides by that rule, they'll get along just fine.
