Regions
Tenebrous Isle, region by region.
Tenebrous Isle is a hub-and-spoke world: Ossex sits at the centre — shop, upgrade and fast-travel — and each themed region branches off, looping back to the hub. Here's what each one holds. For a pin-by-pin interactive map, we link out to the best community ones below rather than reinvent them.
