Aether

Aether is manipulated by Antediluvian machinery, is what gods are made of, and is the food lemures and lares persist off—which they often get from eating humans. Since lemures feed on darklings, they must have it. A person’s presence in the aether is not the same as their soul, but getting at someone’s aether presence can allow a god to get at their soul. Aether seals can be used involving sacrifices of souls, which the Leopard Society does en masse. Aether machinery has many uses, from hiding islands to surveilling them. Aether is apparently influenced by perception. Dead gods leave dangerous impressions in the aether.
