Idea for Backstory:
Gutta Darkmoon's Tribe was in dire shape, The war with Urik was draining their resources faster than they could be replaced, as the trade caravans between Tyr and Urik were drying up. Willing to do anythingt o keep the tribe Running, Guuta went to the veiled Alliance for help. They would supply her tribe with food, weapons, and armor, in exchange for smuggling messages between the two cities. Guuta's Agreement to save her Tribe backfired, and ended in their doom.
After a few of the smuggling runs, Her tribe was set upon by Templars from Urik, and wiped out. Only Gutta Was able to escape, abet badly wounded. Mending herself as best she could, Gutta headed for Tyr, determined to Deliver a message her Tribe paid for with their Lives. She was Impressed with herself, She made it quite far into the Wastes before her legs gave out. As she crashed into the sands, Gutta thought she could see a village in the Distance.
I kinda like the idea of someone within the tribe betraying them, but thats up to you.
