Nizrin clearly didn't develop mentally well.
She has an incredible talent, but has no real formal training to develop it (still impressive the level she reached without such training). Her moral standards are skewed, so she just goes along with the stupidity from a fanatic because she has never known better than just her survival instincts.
Her frame of comparison is warped to say the least, that is why she so easily accepts the shit from the crazy cultist elf.
Don't know if she can turn her life around, but I do hope she can.
........................ What the fuck am I saying... obviously she can... she will get tentacled, and all will be well.
