Ghoul Ward

A 'ghoul ward' is the name given to a stone specifically imbued with magic to deter undead (normally non-corporeal evil spirits) from leaving their place of haunting.

A ghoul ward is normally a broad flat stone, inscribed with a series of cryptic runes.

The effectiveness of ghoul wards has long been a subject of debate in the magic-using community.

Nevertheless, the appearance of a ghoul ward should serve as a stark warning to even the boldest of adventures -- proceed with caution!
