Skull Key

The Skull Key is an item in Harmony of Dissonance. It allows Juste to open doors marked with a skull. This was necessary to complete the game.

It was intended to reappear in Aria of Sorrow, but the idea was eventually discarded. However, although not obvious, there were a few skull-marked doors in the game, one in the Top Floor and one in the Castle Corridor. While the door in the Top Floor would prove useless, as it leads to an already-accessible room, the Castle Corridor door would lead outside the castle. The item is still obtainable using cheating devices.
