In Aethelgard, your class is everything. Kaelen Vance awakened the absolute worst: a Level 1 “Mana-Transfusionist.” Used as a living mana-battery and treated like trash by the Holy Church, his life was meant to be brief and brutal.

Betrayed by his party and thrown into an Abyssal dungeon to die as monster bait, Kaelen discovers a forbidden grimoire.

In the dark, he learns a terrifying truth. His class isn't trash. It is an ancient,

suppressed heresy. He isn't a Transfusionist. He is a Mana-Binder.

Across the realm, the strongest women—sainted Paladins, elven assassins, and dragon royalty—are dying from a lethal “Abyssal Corruption.” Holy magic cannot cure them. Only Kaelen can.

Through forbidden, deeply intimate rituals of Mana-Bonding, he can draw the poison from their very souls.

But there is a catch. Every time Kaelen cures a partner, he permanently copies their stats, steals their unique magic, and adds their strength to his own.

Starting with a fallen Paladin as his first bond, Kaelen begins his ascent. He will build a hidden underground sanctuary for the realm's most dangerous beauties. Armed with a devoted harem of goddesses and their combined powers, he is going to tear the Holy Church to the ground.
