The Temple of Souls is a location in Hyrule Warriors. The temple is Cia's domain, littered with tributes to the three incarnations of Link, specifically Young Link from The Legend of Zelda: Ocarina of Time, Wolf Link from The Legend of Zelda: Twilight Princess, and the first incarnation from The Legend of Zelda: Skyward Sword. The exterior of the temple is a wild rose garden and inside has wide hallways, several of which are significantly distorted possibly due to the sorceress's corruption.
In the main story, the Hyrulean Army attacks the temple after Cia's lieutenant Wizzro reveals her whereabouts. Link, having recently acquired the Master Sword, begins to recklessly charge at his enemies and overexert himself. The sorceress uses this to her advantage to pull multiple dark clones from Link's heart. While the two sides fight, Ganondorf attacks to take Cia's Triforce piece in the midst of the chaos. Both Cia's forces and the Hyrulean Army retreat from the Temple before Ganondorf's army overwhelms them.
It is later revisited during the Wind Waker portion of the story in Legends, due to Cia being tracked there. During this time, Link, Lana, Tetra, and Daphnes Nohansen Hyrule have to defend the weakened Cia from Dark Cia as well as several of her monsters, at least until Cia recovers.
