Beneath Hyrule Castle

is a location in.

Features and Overview
After TotK: starts to seep out from below TotK: and makes nearby people fall ill, TotK: tasks TotK: and TotK: with investigating the source, which originates in a tunnel system deep TotK:. Entry to the tunnels TotK: is forbidden, though the reason why has been lost to history.

Upon arrival, TotK: notes that the concentration of TotK: found TotK: is relatively mild in spite of the effects it has on the people of the TotK:. While investigating, TotK: discovers signs of NaN Zonai Ruins belonging to the ancient TotK: people and excitedly documents her findings with the TotK:. She eventually comes across a series of murals, which she deduces must be about the origin of TotK: and the TotK: that followed.

As they descend further down TotK:, the TotK: grows thicker. Eventually, they stumble upon a mummified body held in place by a TotK:. This TotK: releases its grip on the body when TotK: approaches, causing the TotK: on the back of its hand to fall to TotK:'s feet. When she picks it up, the mummy awakens and attacks with tendrils of TotK:. While defending her against the TotK:, TotK:'s TotK: is heavily damaged and breaks. Before they can muster a counterattack against the mummy, he launches a burst of TotK: upwards, tearing the earth surrounding most of TotK: and sending it into the TotK:. This also causes the ground beneath the three of them to give way, sending them all into freefall. The TotK: in TotK:'s possession begins to glow, causing her to disappear. TotK: is saved by the TotK:, which TotK: him away to the TotK: atop the TotK:.

In the distant past, TotK: leads the TotK: in a battle against TotK: TotK: to bring an end to the TotK:. With no other choice but to sacrifice himself, TotK: relies on the TotK: to distract the TotK: long enough to grab hold of his chest and bind his heart, simultaneously draining his TotK: in the process. This sacrifice traps both of them in place for millennia while TotK: waits for TotK: and TotK: to arrive in the TotK:, where they can destroy TotK: with the TotK:.
