#*appears without warning*

Well, given how unbelievably long it's been since this ask was sent in, I doubt you need or want this answer anymore, Anon. However, I remembered this blog exists, and kind of miss it, so I will answer old asks for my own peace of mind.

Powers for Tashmarine:

• Water related abilities - The name Tashmarine comes from 'Tash' from 'Tashkent' where the stone was discovered, and 'marine' meaning, well, ocean or water. Maybe something like purifying water, controlling bubbles, turning their form into water, or weather related powers could work.

•Blood manipulation - some believe that Diopside, the family of stones Tashmarine is part of, helps with blood health. However, this power may not make much sense to you as gems have no blood. You could perhaps stretch this concept a little and give your Tashmarine abilities such as;

•Possession or controlling other's bodies,

•Energy control, be it in all livings things or just gems. If they were strong enough, maybe they could knock out a being instantly, or revert a gem's form to a smaller size.

As for Homeworld roles, if we take into consideration the possible abilities above:

•Overseeing the plans for terraforming of planets, or assuring they are safe to be colonised.

•If you want the water purification ability, they could make sure places like Sea Spires and Reefs are safe from water damage.

•Gem surgeon - this is a bit of a silly one, but I like it. As I imagine gems with profound healing abilities might not always be easy to come by, especially for serious injuries, perhaps a Tashmarine could work on temporary fixes for injuries like cracks or chips.

•Lastly, for the possession abilities, I feel like an interrogator would be a very fun role. They could force gems to talk, or even from a dramatic story perspective, you could have a Tashmarine who possessed a gem so they could commit a crime themselves, unnoticed.
