It is not easy being a half orc in an orc tribe. It is also not easy being a witch. Agatha was chosen by the tribal witch as one of her apprentices, and like, already hard, got harder.
Witches lead an odd existence in the tribe. They are looked down upon as no warriors, yet respected for their powers and perspective. And feared for their curses. They live separately somewhat from the tribe, but are close at hand. No witch would ever be able to lead a raid, or a tribe, but a wise leader keeps them around. The women of the tribe have little voice in its deliberations, except for priestesses of Luthric...and witches. And their advice is useful, tending to be more thoughtful.
The priests (except those of Luthric) don't like them, seeing them as a challenge, and yet...They are useful. They tend to worship luthric, goddess of caves and women, though they respect both Shaargas and Yutrus due to their portfolios.
Agatha's apprenticeship, like other witches, had a hard apprenticeship. She was whipped for mistakes both real and imagined. But she learned, and her mistress was pleased with the asset she was creating. Agatha and her "sisters" found company and strength together, and her mistress, her "mother" reinforced this. The bond forged was strong. She learned that the role of a witch was important, and eventually greatly respected. And feared of course.
And now war was near. Not just a raid or a battle. But a great war. And she and her sisters are needed. The coven has called and she will answer.
