While Neuroform has paired items, Earthly Form often has more than two in each category. Baseline is all the left-hand items below.
Physical / Energy Being / Phased Out
Balanced / Aspected / Manavore
Single / Swarm
Born / Sprung Full-Grown / Constructed
Biped / Animal / Dragon
Embodied / Possessing
"Balanced" means you're overall balanced when it comes to magical flow. Aspected means you've got some kind of serious distinctive touch, like water or death or runes, that goes beyond just cosmetic. Manavores eat magic. It's occasionally useful, but mostly a fairly serious disadvantage.
"Biped" means you've got fine manipulators. Animal means you don't. "Dragon" also counts other large inherently-magical creatures like Sphinxes and such (and has fine manipulators). I'll figure out better names for this set later.
As an example, if you want to play a ghost, you're Phased Out, Aspected (toward death), Single, Born, Biped. You're Embodied if you can take on a ghostly shape, and Possessing if you have to jump from host to host.
Note that this game has no Sovereign/Slaved pairing. That's intentional, and it's part of the Gift. Autonomous/Parasitic is also not on this list. Embodied/Possessing is similar, but not quite the same thing, partially because you can't possess without someone's permission (again, part of the Gift).
