Threads of Fate is a 1999 action platform video game developed and published by Square for the PlayStation console. It revolves around two characters, Rue and Mint, and their quest for a mystical object known only as "the Relic" that has the power to profoundly alter their lives. Two amazing adventures! Rue is on a quest to revive a lost friend. Mint is seeking power and revenge. Both of them are looking for a powerful relic, but which will be brave and clever enough to reach their goal? Explore a beautifully rendered 3D world with challenging puzzles, unusual enemies, and unknown dangers. Play as both characters to encounter two entirely different storylines. Rue has the ability to shape-shift into the forms of defeated enemies. Mint can learn and use a wide variety of magic spells.

Valen created the relic so he could alter the universe in his own image, but he was destroyed in the process. The relic was then sealed so that no one could use such power for their own selfish ambitions. The East Heaven Kingdom was entrusted to keep such a dangerous relic from anyone who wished to use it. In their quest, both Mint and Rue search for the relic so they can use it for different reasons. Mint wants to use the Dewprism for world domination, while Rue wants to use its powers to resurrect Claire. Yet another person seeking the relic's power is Doll Master, who wants to resurrect his master, Valen, so he could finish his mission.
