I'll echo the point on the writing style. The abuse of commas hurts my eyes, frankly. An easier way to get the point across that she's an alien space-elf is to use very formal language and syntax. Avoid words like "stuff" and "thing" and don't use contractions (you are vs you're).

"The Path of the Fallen comes with a psychic mark that warns all of my kin not to approach and to slay me, should I come too close. There is no hiding from my crime among my own kind. I was forced to seek company with... lesser creatures."

For example.
