The Trailing Vessel

The Void consumes all, erase all hopes and dreams, devours existence itself, and most importantly, it has no mind. Ideals, life, gods, stories, fate, sickness, these will all fade one day, and all it will be in the end...is in the cold Void.

It's a concept, the end of all things, but it has a master. A lonely Knight took on the herald to become the very Vessel to contain this primordial concept in order to save his little sister, and little brother.

But in doing so, made it gave up it shell to become the Shade Lord, and freeing thousands of his fallen Siblings from the duty to Seal the already contained Radiance.

In one moment when he's wandering the pitch darkness, a light like the Radiance, appear deep in the very Abyss it resides in. It couldn't react before the light blips into it and as it know it, the Shade Lord was on a bench, and it noticed the Shell it once discarded has return.

It realized, it wasn't in the Void nor Hallownest anymore.
