About the Game

In an era of fading magic, an endless tide of the undead has risen from the abyss, extinguishing all life in its path.

As the last Lord of the Forgotten City, you must take up the ancient mantle. Awaken the Rune Grimoire hidden deep within the leylines and summon legendary heroes from across time to stand by your side. Defend the last light of humanity against the eternal night!

The fate of the kingdom and the survival of civilization rest in your hands.

◆ Tower Defense Meets Deck-Building & Roguelike Break the mold of traditional tower defense! By combining pre-battle deck construction with randomized, roguelike elements, every run is filled with unpredictable challenges and infinite possibilities. There is no single "invincible" setup—only ultimate strategies that adapt to the ever-changing battlefield.

◆ Recruit Legendary Heroes & Trigger Synergies Summon a diverse roster of heroes, each with unique traits. Combine different heroes to trigger powerful synergies and devastating battlefield effects. Utilize the deep "Multiple Evolution" system to push your core companions beyond their limits, turning them into unstoppable forces on the frontlines.

◆ Deep Customization: Runes & Skill Decks Navigate extensive talent trees and unlock a massive arsenal of skill cards. Freely mix and match your customized deck with ancient Runes to forge a defensive playstyle (Build) tailored to you. Strategically counter bizarre stage mechanics and obliterate formidable bosses.

◆ Turn the Tide with Randomized Gems Discover the unique Gem system that grants diverse stat bonuses. The RNG drops and strategic combinations of these gems can produce unexpected, game-changing effects, ensuring the mid-to-late game combat remains fresh, strategic, and highly engaging.
