Before losing her right hand, Sintrellia had led a fulfilling life in the City of Unyielding Silk. In this hotbed of conspiracy and bloodshed, masters of deceit thrived — and Sintrellia was among the very best. Many families' rise and fall had her shadow behind them. Her pleasure lay not in seeking more power and profit, but in witnessing how her whims caused massive upheavals in others' fates. With just a touch of temptation, a dash of coercion, the noble could fall to ruin, while a street thug could rise as a tycoon. Their sudden shifts between joy and despair were the highlight of the performance. Until she tried to draw Quaesitia into her scheme, she finally miscalculated — the cold general found the puppet master, swung her blade to sever her arm, banishing her from the underground. "How surprising, I thought you might spare a thought for our past camaraderie." "I long forgot such useless things."

Perhaps even the Spider Mother recognized her talent — her right arm, reforged with spider blood, gave her the ability to touch the threads of others' fates. Just a gentle tug at the right point, and their destinies would take entirely different paths. The world unfolded before her like a chessboard, and she was instantly captivated by the game. Which piece to move first, to promote it in several moves? Which piece to capture first, to let another dominate the endgame? Power, desire, human hearts, emotions... all the hidden, intricate rules were drawn into her calculations, weaving the endings she sought. She wandered, effortlessly rewriting the fate of a child or an entire city. And in the North, she found an interesting prey.

Sintrellia had plenty of reasons to twist Alphanarsy's fate, dragging him into the abyss. For instance, she needed a capable undead servant, and someone had offered a good price for his life. But most importantly, that distant glimpse in Golitsyn's royal city showed her this young prince's future. He would become the nation's hero, receiving the Ironfrost Crown from his loving father, becoming a great king. How boring. She decided to twist his fate. She wanted to see this hero err, stumble, weep; see his foolish kindness lead him into traps, abandoned by all. She didn't even need much effort — just disguising herself as enthusiastic commoners, this approachable prince would have no defenses — in fate's hunting ground, the butterfly's wings were pierced by the hunter's arrow. No ability to escape. Before it all happened, there was no hatred between them, there was... just a bit of curiosity.
