Bezu

Bezu is a beautiful ocean world where the breeze is balmy and the water's warm. Full of life and color, it's heavily influenced by the spontaneous blasts of magical power that erupt from its core, which are channeled up and out through enormous natural tubes.

Bezu is composed of three layers: Heartside (the underbelly), Waveside (the oceanic surface layer), and Ventside (the over-layer, made up of networks of pipes high in the air).

Heartside

Closest to the core is Bezu's underbelly, Heartside, a huge underground network of tunnels and vents. Heartside is very hot, and is primarily occupied by dwarves and orcs, who are evolved with the thick skin and darkvision necessary to navigate a world prone to randomly melting or blasting fire or magic in your face. Most Heartsiders are happy to stay down there, but visitors come back telling stories of enormous metal cities built into the caverns there.

Waveside

Waveside, the surface, is the most diverse and populated layer of Bezu. A huge ocean with dozens or hundreds of islands scattered across it, all of Waveside enjoys the benefits of a magically heated core - just about everywhere on the planet is warm, breezy, and beautiful. Islands with more stable vents have attracted enough people to build cities, while smaller islands whose vents have less predictable magic are often home to bizarre landscapes, animals, and even puzzles. There are thousands of ships roaming Waveside, from simple fishing boats to entire city-sized fleets. Humans, gnomes, tabaxi, and merfolk are all native to Waveside, but the largest cities are home to all races.

Ventside

Ventside is the airborne layer of civilization, composed of vents: sometimes in strange, island-like nests, other times in huge but thin-spread networks. Ventside is cooler than Waveside, and its vents erupt far less frequently. However, strange objects sometimes rise up, things that seem useless or dangerous or simply incomprehensible, and Ventsiders are known to either incorporate them into their beautiful, alien sky cities, or failing that, to simply eject them. Others think of Ventsiders as watchful, nervous, and weird. Elves, halflings, and aarakocra are native to Ventside. Although other races can survive there, few people choose to live among the vents.
