You have found the Shard of Memory!

Before their untimely death, Weslahdonna and her Knight shared one final moment.

The Shard of Memory begins to glow and show an image of the two lovers

…

“Forever… promise me… forever-!”

Weslahdonna cried out. But as her physical body died, her astral body was cast into a giant crystal.

As her spirit is trapped within the crystal- she lets out one final spell:

“ENCAPSULATUM PERPETUUM!”

…

The memory ends and the Shard goes dim.
