The World of Adratha
Adratha is my homebrew setting for Pathfinder 2e, though it could also work in most other high fantasy game systems. Frankly, it's mostly in PF2E because that's my current favorite system for high fantasy adventuring.
Like the canon setting for Pathfinder, Adratha is a high-magic setting. It borrows some influence from Final Fantasy as well--airships are relatively common, and crystalline magic is a core part of enchanting items. Leylines are also a central part of the setting: in times past, the leylines were badly damaged, leading to a cataclysm that still affects the world today.
Details on the world are available below.
