Plague Pilgrimage

Plague pilgrimages are journeys that the uniquely sick and afflicted undertake in search of treatement. While most basic maladies can be treated by a doctor, alchemist, or a cleric if you're wealthy, Vorago is full of mysterious "illnesses" which need rare and specific treatment. Some of these rare maladies are just that, rare mundane diseases, but most pilgimage-worthy illnesses are magical in some way. In this case, specialists in magical medicine will need to devise experimental treatments, which often use rare ingredients and cost a fortune.
Some examples of pilgrimage-prompting plights would be: curses from witches, strange organ failures/modifications due to irresponsible practice of magic or alchemy, madness induced by botched divination, magic burns which do not heal, curses from an offended god who is now outside the Cycle of the Gods but whose curse remains, and residual spell effects.

History

People seeking treatment for strange problems has never been new, but the frequency of such problems skyrocketed after the Destabilization. As such, seeking treatment has gone from a mundane misfortune to a recognized phenomenon with its own connotatons and traditions; like a refugee crisis, the pity of the charitable quickly turns to contempt when exposed to too much volume. "Plague Pilgrims" are not welcome inside the main parts of settlements, regardless of their affliction's contaigion risk, without much explanation, and are expected to stay in lower-quality spaces. Obviously, this prejudice is most present for visible illness and disability.

Execution

Pilgrims are expected to head to Plaguetown to seek treatment under their own power, even if it means going on foot; despite the fact that many capable healers live in other less overstuffed settlements, uninformed pilgrims will make the longer journey to Plaguetown simply because "it's where they're supposed to go". In plaguetown, they seek counsel from any number of doctors, alchemists, and charlatans, treatment from the monks of the Way of Bodily Harmony if they are lucky, or succor from the temples of the gods of disease if they are especially unlucky.
If their malady can't be immediately treated, they are often sent by their counsel on a quest to find a cure. This may be as simple as being referred to another doctor or cleric in another place, or as complex as harvesting phoenix feathers or dragon's blood. The proposed cure may or may not actually be helpful either, sometimes it's just a way to get the patient away and give them hope.

Observance

The emergent plague pilgrimage tradition is contested by those with a moral opposition to forcing the sick to take care of themselves. Whether their goodwill can shift the cultural consciousness away from this new entropically favorable tradition of "self reliance" remains to be seen.
