If Life encompasses Nature, then how far does that go? Is Weather part of Nature, or does that tip more into Breath because of Wind? Does Nature in terms of Life encompass plants? Animals? Creatures? Anything that's alive, or was ever alive? Could a Life player be a Necromancer and raise an army of the dead? Basically what kind of power falls under the Life aspect?
Do remember that Aspects don’t necessarily need to be isolated from each other, some things the Aspects are related to may overlap with others. Breath could be a good candidate for weather effects- As would Space merely on the grounds that a Space Player could definitely also control wind currents because they’re things in the physical space they are. Specifically talking about Nature? I actually have a friend who, as the Knight of Life, used Lightning as a weapon, so I may be biased in saying that, yeah weather could be Life-y, although also Doom-y now that I think about it. I also have a Fantroll Bronzeblood that communed with plants instead of animals, fitting his Life theme, so I may ALSO be biased in saying that, creatures, beasts and plants may fall under Life as well. In the end, Aspects relate more to what you think they relate to thank you may think, they’re concepts and you can draw a lot from them!
That being said, a Life Player would TOTALLY be able to become a Necromancer, however I see their Necromancy to be more like… Mindless Zombies. Leave it to a Heart Player to raise the Dead with their Soul still intact.
