Innate Magic
Innate magic is commonly understood to a by-product of thought and intent. When a creature directs its will towards a task, it excites an energy that is within every creature, and through practice, repetition, training, and pushing ones limits again and again, this energy slowly becomes stronger, more defined, and more easily controlled.
From the farmer to the greatest sorcerer, everyone channels innate magic in their own unique way. This magic follows five broad classifications; practised, external, natural, emotive, and kinetic. Though it should be noted, most individual usage of innate magic falls within these as spectrums rather than as specific pillars.
Practised magic is that which is defined by rigorous and rote training. This includes disciplines such as a wizard casting spells learned from a book, a thaumaturge applying and amplifying the effect of learned weaknesses in an opponent, and alchemists and inventors manipulating the mundane in precise ways to create fantastic effects. A magus would also fall under this classification, being a user of both kinetic and practised magic, as would some psychics who rely on precision and control of their mental acuity rather than instinctive outbursts.
External magic is channelled from a patron, eidolon or other outward force using oneself as a conduit. Followers of a faith or patron like a cleric or witch, and individuals with an empathic connection to a being or beings like a summoner or animist. This form of innate magic is blended with the others far more often, however, and many lean on external magic to some extent, such as champions who follow a faith, oracles cursed by a powerful outer force, and sorcerers with a connection to divine or diabolic creatures.
Natural magic is that which blends almost seamlessly with Sevess' natural flora and fauna, and leans on the power found within. Druids are the obvious example here, being persons fully immersed in and at harmony with nature, but kineticists, who bend the elements, as well as certain breeds of oracles, sorcerers, and summoners whose curses, bloodlines, or eidolons have a particular attachment to the world.
Emotive magic is much more instinctive than the product of rote practice, but usage of it increases one's control all the same. Sorcerers with their inherited capabilities, bards with their free-flowing blend of art and magic, certain psychics with natural capabilities, many oracles who channel their curses through instinct, and champions who do not follow a particular faith all fall under the banner of emotive magic.
Kinetic magic is the most common, being innate magic built through physical conditioning first and foremost. Warriors of all creeds - fighters, monks, swashbucklers, guardians, commanders, rangers, rogues, and barbarians all rely primarily on kinetic magic, while champions, magus, kineticists, and summoners all blend it with another classification of magic in equal measure. All superhuman feats of speed, dexterity, strength, and resilience are reliant on kinetic magic, and almost everyone has channelled it to some degree in their life.
For Players:
Innate magic is the explanation for your characters' capability to do amazing things, and is roughly analogous to Pathfinders' magic types, just renamed and redefined to better fit the lore of Sevess. The system is not changed mechanically by this, and when talking specifically about game mechanics or character builds, it will generally be easier to use Pathfinder's classifications. However, if you want to remap something to the Sevess loreset, 9/10 times you can use the following swaps:
- Arcane = Practised
- Divine/Occult = External
- Primal = Natural
Emotive and kinetic don't have direct analogues in the PF2e system, but the examples given in the descriptions above should be more than enough to grok the type of innate magic someone is using for lore discussion purposes.
