I'm working on my fantasy setting and want to split the Knowledge skill into three. The problem is that I'm not sure how exactly to divide it.
I'm looking at Lore and History , but can't think of a third.
Lore
Lore is the knowledge of magic and the occult. It is the skill that grants boons on magic spells (instead of the Knowledge skill). You roll Lore when you're trying to identify a magical artefact, determine the nature of a magical creature or unravel the effects of an ongoing spell.
History
History is the skill that reminds you of what's come before and how it impacts modern life. Stories of old kingdoms, battles and lost languages are all facets of the History skill. Indeed, a character is assumed to be illiterate unless they have at least 1 rank in History.
Make History checks when you try to recall why an outpost was abandoned, what a mural on the walls is trying to convey or what the appropriate religious rituals are.
But what about the third Knowledge skill? I'm going for three because that's a recurring theme when subdividing skills: brawl, melee (light), melee (heavy); driving, operating, piloting; gunnery, ranged (light), ranged (heavy); arcana, divine, primal.
I don't want a Forbidden skill since forbidden things can be magical or mundane (Lore or History). I'm thinking Cultures, as the current analogue of History. But I'm not sold on that one.
Thoughts?
