how would one consecrate a graveyard/cemetary for safe cauldron spilling?

[Plane]

PF2pg 106 (right column) "The Enchanted Cauldron" of a wizard can only be safely spilled in a graveyard (top of column) or cemetary (bottom of column) or else you get ghosts (haunting entities) released as a nuisance. This happens if there's accidental spillage of only three of the six pints of blood (half of it)

That begs the question of how we go about defining what a graveyard or cemetary is. Is it anywhere there's a corpse buried? How close does the blood need to fall to a corpse? Does a priest need to lay them to rest with prayer? What's the radius?

This lead me to look for other uses of the term in the book:

pg 28 (phobia) "Graveyards/Tombs/Burial Mounds"
pg 66 (exorcism) "A successful exorcism performed in an area such as a graveyard, tomb, etc., will destroy all animated skeletons, corpses, and mummies which inhabit the area"
pg 212 (create zombie) "must be done secretly in a graveyard, burial place or battlefield littered with bodies"

There's various blessings/prayers on page 65 so I'm wondering if we could just borrow something there in terms of defining what creates a graveyard/cemetary assuming there's some level of supernatural component of it which creates that whole "cauldron-safe" status.

Blessings take 15 seconds to do and last 2D4 weeks for example and one of the uses is "blessings of a home" which keeps ghosts/fairies out. There isn't exactly a radius/range listed. If we want a longer effect, Exorcism takes 1D6 hours to perform but the effects last 6 months, but this is still lacking stuff like "area effect" or "range".

I notice this happens a lot for priests, like Turn Dead doesn't have a range either, just an activation time of 30 seconds. The spell Turn Dead is 60ft so I figure just use that... and similarly the Exorcism spell is 30ft so maybe use that for the priest ability too?

Priests aside I figure any mage who knows spells like these (Exorcism or Turn Dead) or even a non-mage with a scroll allowing these spells, could also use them to effectively consegrate a grave site after burying a corpse, and we can handwaive that as "hey you created a temporary cemetary"

I feel like we do need time limits and area limits and PPE costs though because otherwise you eventually encounter problems like "literally everywhere is a cemetary" because 10,000 years ago a rat died and became part of the mineral composition of the soil your cornfield is planted on.

The Megaverse runs on vibes.

That said, I would classify a graveyard as a place where multiple people are buried on purpose, with a degree of respect, often with religious ritual. A rat died 10,000 years ago, no. A crossroads where someone is buried as a punishment? No. A place where a bandit died a month ago? No. A place where people bury their dead pets? Yeah (though it pushes "people" a bit).

It takes more than just a buried corpse or three to make a graveyard. Graveyards are more than just a place where the dead are buried. They are essentially considered an extension of a church, both from a real estate point of view as well as a spiritual one, specifically constructed for the purpose of properly interring the dead of the faithful.
Of course graveyards aren't just fenced in fields of headstones and actually come in a variety of styles from classic walled fields to miles of underground vaults to huge, monolithic structures ( the Pyramids of Giza are burial sites, ie 'graveyards').
So how does one 'consecrate' a graveyard? I imagine it would be much like the consecration of a church once construction of the site is complete. Priest in charge with a few lackey priests behind him making speeches and spouting nonsense about pride in the people and honoring the gods and remembering the fallen and faithful. Then, once somebody of the church dies.... Plant them in it.

Priests of the Church of light get access to a miracle of consecration which consecrates the temple.
