Deep within the labyrinthine twists of metaspace, there is an immense sphere of crystallized needles which represents the idealized platonic form of physical suffering. This sphere is several hundred miles in diameter and floats in the space between realities. As you get closer and closer to the crystal, you begin to feel pain. This pain increases exponentially the closer and closer you get to the epicenter of the crystal. There is no physical damage dealt, but the effect is still immense. No one has ever managed to touch the crystal, as no one has ever gotten within a mile of its surface without turning back, dying of shock, or committing suicide. There are several religions and philosophical doctrines which prominently feature the crystal, and their outposts circle it from a safe distance.
One of these groups is known as the Contentment Relativists. They are not masochists, though this is a common assumption. They wear simple robes and eat simple fare. They accept all peoples from all walks of life, and conversion is not required to make a pilgrimage towards the crystal. They do not worship the crystal, but they do make use of it as a physical proof-of-concept for their specific worldview. According to them, the key to happiness is context. By framing everything in the perspective of the worst thing you have ever experienced, you will find yourself able to remain upbeat in even the lowest of valleys. No matter how awful your current situation, you can find some small amount of solace in the fact that things are not as bad as they once were.
