Alright, good work both of you. Hopefully Ayden will catch up soon. One more after that and we can move on to the next stage - though new people would still be welcome to apply indefinitely.
Ekirei, I'm a bit on the fence about Vermin, since it kind of applies to Vorcha as a keyword anyway. That said, most vorcha don't exactly aim high, and so would not be hampered by it nearly as much as him, so I guess it works.
As for Abilities, Technical Knowledge and Biotics naturally fall under the Sentinel keyword as it is, so you may want to redefine them or even just take some other ability instead? Technical Knowledge, from your description, could be replaced with something like Scavenger or Junk Technician, or something else to emphasise the low-tech nature of his ability. Biotics could be replaced with Telekinetic if you want to keep a redundant biotic ability (redundant abilities can come in handy, in a way I will elaborate on later).
