[2022] Magic research?

You can find Arcana tomes in underground dungeons, on raiding bandits, and in merchant inventories.

You can also make tomes at the Library, but you need to unlock the research with Arcana tomes.

Ya, if you're playing Humans, it's supposed to be much more challenging as they aren't one of the naturally magic races.

Ya, from a gameplay mechanics standpoint, it's intended for them to be basic relative to other races. I will be adding some more depth to them regarding personalities and individual histories. Well, I'll be adding this sort of thing to all the races, but each race will have their own unique likes/dislikes, and cultural biases. But, I don't plan on changing the mechanics of the Human race.
