Corruption of the Sun

One dies, unable to fulfill his quest, and later looses a close companion...
The second looses his mind while on his 'crusade' and later dies by an unknown force...
The last is pulled into a force of unknown possibilities after loosing his own soul to a battle of Lothric...
All conveniently end up in the same area.
Only this time, they're looking for a peaceful life
Not everyone gets what they want...
