(Tear Away) Death-Cloaked Cordella

Lore
Cordella had determined the curse's origin to be within the ruins of the former royal castle. When she passed through the crumbling halls, she was overcome with nostalgia. Though the effect of the curse was fearsome, its weak point lied in its composition. The princess cast a simple light spell upon the perpetually shaded artifact and it dissolved in the blink of an eye. As dawn broke outside, the shambling undead deprived of their protection also vanished under the sun's rays. Cordella then cast aside her funeral cloak, for the destruction of those she had deceived rendered it unnecessary. "My kingdom has been freed."
