Heart of D'Sparil

The Heart of D'Sparil is a puzzle item available in Hexen level Bright Crucible. It is the heart of D'Sparil, final boss of Heretic, brother of Hexen's final boss Korax and youngest of the three Serpent Riders (D'Sparil, Korax and Eidolon). Since it is used in a secret level, the reference to D'Sparil is considered an easter egg.

The Heart is found again in Constable's Gate in Hexen's expansion Deathkings of the Dark Citadel.

The heart appears like a red gem (in the image the heart is onto the pedestal where it has to be put).
