“O ___ mine”, used by Ahamkara, Worm Gods And Calus, invokes a principle called the Anthem Anatheme. In this, the target is put in the cage of “o” and “mine”, and reality is changed to match the target’s desire. The being that spoke to us in Mara’s Court said that the Ahamkara and the Worm Gods are NOT related, and evolved separately to exploit the Anthem Anatheme, making them rivals. It’s unclear how Calus knows it, but it’s possible the Darkness taught him. Key words: NOT RELATED, EVOLVED SEPARATELY. Edit: Here’s the lore card, brought to my attention by KSeth27, asudeM from Truth to Power. Further explains how the Worm Gods and Ahamkara are actually different. “I've been correlating information on the Ahamkara and the Hive worm parasites. Both display a peculiar ability to convert the host's intent into an ontomorphic, reality-altering effect. Both use similar language in their appeal to the host. I don't think they're the same species, however. The Hive worms spawn large numbers of young from relatively few adults, always display the same physical form, and live in communal groups. The Ahamkara are solitary, elusive, and seem to alter form to suit (or confuse) expectations. The shared syntax "o ___ mine" may be the key—it seems to be a shibboleth used to invoke an ontomorphic effect, placing the target in a cage of "o" (activational, specific, appealing, and naming) and "mine" (defining ownership and subordination). Ahamkara and worm may have evolved separately to exploit this effect, just as many species independently evolve eyes. This might place them in competition for the same ecological niche. I would expect a rivalry or antipathy between them.”
