From publisher blurb:
Blood, grit, and survival are at the fore in these primordial lands.
If you like Conan the Barbarian, Xena the Warrior Princess, Tarzan, Fafrhd, Khal Drogo, Thundarr, Red Sonja, Grognar, the Scorpion King, Beowulf, Kull the Conqueror, Fire and Ice, or are just a fan of savage adventures on a primal and untamed world—Vast Kaviya is for you!
This super massive world of primal struggle is a decentralized campaign setting and bestiary (22 areas with 100+ statblocks) for D&D 5th Edition. Within are 21 different warlords all with their own lairs, minions, and guidelines for how they interact with one another, giving GMs a new toolbox of NPCs and unique areas to either include in their homebrew fantasy setting for some old school sword and sorcery, or to gradually discover using the book's Exploration Rules! There are 13 major tenets about the world that are true no matter where one travels however.
In addition to what's in the core 5th Edition rules Vast Kaviya has a variety of new character options for the brave souls that strike out across its countless lands.
- New Races! Joining classics like boggards, gnolls, and mongrelfolk are the plant-like alai, insectile kanca, parasitic ottunni, and saurian taino-kar. There's also new subraces for aasimar (elated, soul, and vindico) as well as genasi (acid, ash, mist, and mud), dwarves (mistdweorg), and halflings (mistling).
- New Class Archetypes! Path of the Psion-Primal barbarians, Lunar clerics, Burning druids, Primal Leader fighters, Pyrokine monks, Oath of Web paladins, Primal Hunter rangers, Savage Poisoner rogues, Animator sorcerers, Dreamer sorcerers, and two new warlock patrons (the Grandmother and Hivemind).
- New Classes! The dual-natured agile warrior gemini class appears here with the atavist, equalist, and reluctant hero balances, and it's got a new archetype that revolves around day and night—the nychthemeron. If you've always wanted to tame a simple-minded creature to go on adventures with (be that an aberration, beast, dragon, monstrosity, or ooze of Intelligence 5 or less), look no further than the monster tamer class! There are also four unique 8 level prestige classes: elementalists that ultimately transform into their chosen element, fractured soul shapeshifters with nuanced control over their bodies, magic-eaters that become tougher and more lethal by rejecting all things supernatural, and primal shamans that unlock primitive psionic powers.
- New Options! Discover who your Amnesiac background adventurer truly is, gain control over slivers of magic using naturally occurring raw mana, or take a feat to embrace your mistdweorg ancestors or the illumination granted by the underground City of Lost's potent Sun Stone—or set your sights on stealing the legendary gemstone!
There's a bestiary chapter with more than thirty different monsters—ranging from the little forvirskrípi to the enormous megawolf—and a host of devastating versions of creatures players will think they already know how to handle, but the real focus of Vast Kaviya is the warlords fighting to carve out more of the world for themselves.
