A roguelike deck-building RPG. Delve into procedurally generated dungeons, hone your deck with a wide array of cards, and fight for survival. Full Steam Workshop support lets you craft and share your own dungeons. But deep in the Void Dungeon, a fate worse than death awaits the women ensnared by the tentacles—to become &quot;seedbeds.

A monstrous threat looms over the kingdom: the &quot;tentacles.&quot; Nesting deep underground, they snatch people away and vanish into the dark. One by one, the dungeons across the land have fallen to the kingdom's finest. But one remains unconquered—the &quot;Void Dungeon,&quot; from which no challenger has ever returned. —One hundred years ago Tanya, the kingdom's mightiest warrior, was ordered to clear the Void Dungeon. She swore to her childhood friend, the princess, that she would return. She never did. Freya, the holy saint, defied her father the king to follow her dearest friend into the dungeon—and was never heard from again. —The present day Reen, a rookie warrior, joined the army to pay for the medicine her frail sister Elna so desperately needed. One night, a massive tentacle drags her sister away. The direction it fled—the Void Dungeon. Plunging in alone, Reen discovers an old diary. &quot;It has been several days since I followed Tanya into the dungeon—&quot; The heroes who vanished a century ago. And yet, nowhere does it say they &quot;died.&quot; What will become of her sister? Are the captured still alive? The desperate struggle of one weak, untested warrior is about to begin.<h2 class="bb_tag" >Roguelike × Deck-Building × Dungeon Crawling</h2>A true roguelike RPG that fuses turn-based dungeon crawling with card combat.
