@DemousBasically just humans, npcs, and kemonomimi.
As for weapons it depends on the fighting class. Though melee is the most diverse with weapons.
Mages only have wands and staves (typical stuff) and use sort of like ammo, runes.
Archers use bows. Longbows, shortbows, crossbows. Throwing weapons such as knives and shuriken.
Warriors can choose from a huge variety of weapons, which everything will be in the main post.
But the most used in the series are:
Scimitars, katanas, zweihanders, kukri, arming swords, and longswords.
