Sister of Silence are actually quite high ranking. They sometimes accompany Primarch or the Emperor and their words (which they write down and not speak) hold great political power. My character purpose would be related to the eldar alliance (some sort of insurance agaisn't them).

The other thing that i wonder if you are willing to consider... Since... Well, there are two missing primarchs, so i will be accepting two OC Primarchs. Maybe one of them could have been a woman, with a competely female Chapter... We're changing a lot already, i don't see why we can't change more.
