Not really, unfortunately. There is still many pieces to the puzzle missing, but at least now you know the score now and can react accordingly if something happens with the coral or those controlling it. My suggestion, try not to think about it and enjoy your time here. But on your guard for anything suspicious.

At the very least take solace in the fact that even if something terrible happens, the coral can fix you up, good as new. All it takes is five days if you die, then you reappear near the coral.
