Green Abyss - Rise of the goblins

Valtira, Serena, and Lyria are three elite members of the Sisterhood of Chains guild, feared and respected throughout the kingdom. But when a rescue mission turns into an ambush, they fall into the hands of a goblin shaman with unknown ambitions. Chained in an underground dungeon, stripped of their magic by ancestral runes, the three girls are subjected to a "training" that has only one purpose: to break them. Between humiliations, temptations, and the slow awakening of desires they never wanted to feel, they must fight not to lose themselves. But in the Green Abyss, the line between resistance and surrender is thin. And the goblins are very, very patient.​
