The Hunger

The Hunger is a sentient plane that feeds on other planes, created from the bitter nihilism of an entire planar system and its inhabitants. It serves as the endgame, main antagonist of the Balance Arc campaign.

The Stolen Century
The Hunger is first encountered by the Red Robes as they are leaving their home planet. It starts attacking and feeding on their plane, forcing them to escape. It is not known how many planes it devoured before reaching the Red Robes' world but from there on it would relentlessly pursue them across space and time.

Cycle One
A year later it finds them again in another plane, and it starts to attack and devour that plane as well. The Red Robes then watch as it grows slightly bigger from devouring the plane and its Light of Creation.

John
Merle would eventually find a way to converse with the Hunger directly and found that it was controlled by a man named John. John reveals that he essentially created the Hunger. He was a philosopher and motivational speaker who came to realize the limitations of being mortal after pondering eternity, and came to believe that "living is horrible." He shared his dissatisfaction and fury with the people of his home plane, and soon everyone and even every thing came to agree with his worldview. It turned them into the Hunger, a force seeking to transcend existence regardless of the cost by chasing the Light of Creation, which allows the Hunger to exist and consume bonds for power.

Story and Song
After the IPRE crew successfully hid the Light of Creation for a decade, The Hunger supposedly lost its way; rather than trying to overcome the laws of reality, it now simply wants to consume everything. John uses Parley to warn Merle that he's no longer in control of The Hunger, and gives him a hint to defeating it - breaking the bonds between it and the planes its consumed - before The Hunger drags him away.
