"A few years back Nebraska was with her Mother returning to a site they were forced to abandon due to regional war, research and all. The violence had passed a month later and on their way back they a tribe raided them at night. Nebraska was able to hide and evade the attack, but her Mother died in the slaughter along with the aides aides and other scholars. Over the next few weeks she lived off the land and traveled alone to the site. She was emotionally broken, in shock, and untrusting of all people. Though camping and hunting had always been a part of her life, perpetually moving from one dig site to another, Nebraska found she had an amazing knack at it. Especially when underground, growing up in cave systems and ruins gave her amazing intuition when moving through them.
Once she got to site she found it had been raided. Nebraska spent a long time there re-excavating alone and mapping the ruins system. Still, with a pathetic fraction of the information that had been raided or destroyed, Nebraska headed out alone to continue her Mother's research and avenge her pain on the tribes that had wronged her."
