A turn-based D&D 5e RPG · in a world that runs itself
Turn-based Dungeons & Dragons 5e, set in a living, generated world that plays on without you. Roll a hero and delve dungeons that build themselves — or take a divine's throne and win the world by moving the mortals in it. Harvest Numa from the faithful and race the Eschaton Cycle before it ends everything.
Play as a mortal hero — or rule as one of three divine powers.
Three powers, one world
Every world is claimed by three rival divinities. None of them can lift a sword — they win only by lifting up mortals.
Humankind
Radiance, covenant and order. Empowers the faithful, consecrates ground, and holds the line with disciplined mortal hosts.
Demonkind
Guile, dread and appetite. Buys loyalty with power, breaks resolve, and floods contested land with faction-spawn.
Beast folk
Verdance, instinct and the wild. Grows its people from the frontier inward, taming the beasts of a world that was theirs first.
Sixteen bloodlines, one rift
Human, elf, dwarf, demon — and the beast folk of a dozen wild lines. Every face is hand-made art; every people carries its own traits, its divine calling, and a taming affinity all its own.
One face from each of the sixteen peoples — drag to explore.
Everything is generated
Full 5e character creation, a whole world spun from a single seed — as a turning globe or a flat map of kingdoms — and dungeons that assemble themselves as you delve.
The game is influence
Power flows one way: from the choices of mortals, up to the god who nudged them — and back down as blessings, boons, and armies.
Whisper a spell, a rite, a rumor into a mortal's moment — and reap Numa from the charge of it.
Spend Numa to consecrate cleared zones. Territory floods outward from your seat, one frontier at a time.
Where two divines' borders touch, the war turns hot — heroes, war-parties, and dungeons that bleed monsters into the land.
When the world tips, the apocalypse votes. The last power standing takes it — and levels up by the worlds it owns.
Two ways to play — you choose
When you enter, you pick your side of the veil: play as a mortal hero, or take the throne of one of the three divine powers and move the world from above.
