Yasondre being sensually spoiled by Anathema.
Anathema's Lore:
Anathema is a soulcatcher who was Esperia's best friend and partner in crime during their time ascending to Dark Seraphim, referred to by most of Heldath as the infamous Scourge Sisters, they were seen as a fearsome duo who were destined for greatness
Once they ascended to Dark Seraphim, they were pulled apart for varying missions, since one Dark Seraph alone was incredibly useful at depopulating entire countries and gathering soul power. During her exploits, Anathema was approached by Yasondre- who had been getting stressed out due to Origin's stranglehold on her sister and the cosmos at large, seeking pleasure to override the pain. After some initial holding back and afraid that Yasondre may be deceiving her, Anathema saw the Demigoddess' plea was genuine and agreed that whenever Yasondre was in need of relaxation and pleasure, Anathema would be happy and ready to grant it, this deal also benefited Anathema in that she had a strong political ally, and an essentially infinite source of soul power- seeing as Demigods are immortal, and cannot ever truly be exhausted of their energies.
Anathema has not caught up to Esperia's serazai form, but is happy to be what she is- every now and then Esperia and her will go at it too for old times sake. The two get on like close friends, and both give each other heck over the other's fetishes, Esperia seems to largely desire red hair, which Anathema possesses, meanwhile Anathema really likes elven ears and green kelpy hair. They both also seem to have a desire for same sex relationships, and men are but a means to soul power for them. Anathema often jokes that Esperia is "into Pep", which Esperia largely abjures, stating that "I'm not going to fuck a cat, I have SOME dignity!"
Esperia's loyalty become solidified to Fyori, the daughter of the demigoddess Blu, and later the Goddess Sacreblu. Together they ascend and Esperia finally reaches her goal of achieving Serazai status.
Meanwhile, Anathema is fixed on Yasondre, she may lack elf ears, but anathema desires her purity and of course, her green leafy hair, most soulcatchers seem to grow fixations relating to their previous targets, with Esperia being after Pep's soul causing her to admire red hair, meanwhile Anathema was sent to depopulate the Kelp Elves of Moiyserr, and it's hinted at heavily that she got her fixation for green hair and leafy garments from them.
While she's never been super relevant in any games, she does make appearances, as an optional boss and later a semi-villainous guide in Menagerie, a supporting character in Hellcat, and a supporting character in Intelligence 314th Clash. So far the only real evidence publicly known of that Yasondre and Anathema are in a relationship is a secret scene in Hellcat: Born Again.
