Hadum, the God of Darkness is said to be connected to the Black Stones, the Black Spirit - and according to a legend of the Ancients, to the fall of Cron Castle. According to the latter, the Immortal Alchemist attempted to summon Hadum in Cron Castle during the reign of Agris III leading to the destruction of the castle in a massive explosion and the death of the King.

The murals seem to indicate that the Alchemist presented Agris a scroll that allowed the ability to summon Hadum, but the ritual where he attempted to do so did not yield the intended immeasurable power for Agris, or at least could not be controlled ...

Statues depicting Hadum can be found in Balenos in several location, for example near the Altar of Agris or North of the Mountain range dividing Serendia and Balenos.
