Interesting. I know the Gravemind is essentially omniscient, but I've never heard the word transsentient used to describe it or anything else. I honestly don't even know what 'beyond sentient' means since I don't know how anyone or anything can be beyond a state of sentience , unless the person or being in question is a god, but the Gravemind isn't. IDK, I personally wouldn't describe the Gravemind as transsentient, just a creature that is almost at the state of omniscience, but I'm probably viewing the word to mean something it's not.
