Well so sticking to the fact that I have never known this was a thing I'll just try my best to guess. So i don't know if the sword in one of the pictures ties in to the enigma but assuming it does judging by the fact that it has a star shape I remember that the Orion had a sword which could link that. The chest piece and shoulders contain glowing orbs which could either be type of spores or many galaxies/stars/constellations grouped up together so my guess would be the word is 'orion' or something of the sort
