It had been so long since she returned to the desert, after Diablo's defeat she thought she could get some peace back home to train other willing monks. However, it was not the case. A new threat arose. Reapers, with the fallen Angel of Wisdom leading them. Malthael. She had briefly seen visages of him now and then, but not personally. Not that she wanted to.
Ishara stood out the outskirts of Caldeum, gaining reprieve away from Westmarch. She was more than capable of handling herself against the hoards of reapers, but she was only human... ish. Nephalem technically. Even she needed a break.
