THE HUNGER is a force of corruption. It consumes and alters everything it touches.
It appears as a shimmering black ooze, it appears like a night sky, stars and nebulas dancing within it. Its beauty is unending.
When consumed or when seeping into wounds of creatures it infests them. It overtakes the mind and controls its host. When something is overtaken by the hunger, it becomes stronger and faster. Often losing its inhibitions.
At first an inhibited creature only seems to follow its vague wants - but once the host has died, the hunger overtakes it in its entirety, and puppeteers around the body of the host.
Night essence, an essence of monster parts and corruption. A shimmering black liquid. Esther's theory was that the corruption made anything it touched stronger. In small amounts, it could make people just as stronger.
