They got out of the dungeon

After leaving the dungeon, Isabella had a little surprise, for although she was being lovey-dovey with Bruno, her internal thoughts were raging at this betrayal of her promise to be Bruno's lover till the day they died. Yet, even with that promise, she couldn't help but use her heightened senses to focus on her aura clone that hadn't yet dissipated and was secretly and lovingly sucking the Goblin's monstrous dick while the two of them pretended that the clone was keeping the Goblin calm after getting out of such a hellhole. Bruno determined that the Goblin harboured no malicious intent and wasn't tied to the dungeon, so, considering his docile nature, Bruno relented to Isabella's pleas to take him back with them. Bruno had no idea that Isabella was still cheating on him ever since that Goblin penetrated her, the clone's heart clearly shifting now that the original was attending to Bruno, giving Isabella a weird, confusing, and embarrassing sense of jealousy towards the clone.

Still, questions came first, even in the initial thralls of lust in Isabella's heart, so she took the two back with her as she eventually got to the Silver Water Phoenix Magic Tower branch in Volka City. The mages then did a bunch of tests and concluded the Love Crest was a special artefact meant to bring one closer to their chosen lover and spice up the relationship, giving them an accidental and secondary boost to their abilities, something they proved after testing Isabella with IQ tests, strength tests, etc. As for the Goblin and clone, whom they named Greeny and Chloe, the mages came to the same conclusion that Greeny wasn't a malicious Goblin and was simply born after a weak adventurer delved too far and got **** to ****, producing Greeny before she died. As for Chloe, although she was an aura clone made from an awakening of sorts, the injection of physical matter and the Love Crest's duplication onto the clone allowed Chloe to not only become pregnant but develop a slightly divergent personality, as is seen in how she talks far less but acts overfilled with joy and love.
