This essence was extracted from the hag Gulk'aush. Her blasphemous love of a human led the Slumbering Coven to curse her with the inability to sleep. The essence throbs with power, and with each pulse you feel a brief wave of sadness.

The essence appears to have a large recession in the middle that has the shape of a gem. Combining this essence with a gem of great power would likely produce an amulet with a power that would rival an artifact's strength.
