Personal Shrines
As everyone in Theoma is either a Greater Divinity (Land God) or a Lesser Divinity (Common Immortal), one of the things that they often do for each other is to erect shrines in devotion. Many houses in Theoma have a pantheon room which contains dedications and open spaces where future dedications might be placed. It's considered a faux pas to fill one's pantheon room too quickly...
In any case, such shrines are erected:
To the Dead
With indefinite lifespans universally available, death is very rare in Theoma. People generally live for as long as they are avoiding death. Fate guides them away from mishap in Benevolent Theomes nearly always, and does so likewise in Negotiable Theomes as long as their alignment with the land god is good. The result is that graveyards are almost (though not quite) unheard of. Instead, it is common practice for the closest friends and immediate relatives of the deceased to build small personal shrines to the departed. This would be too much labor and too much land expenditure were it not for the great protection against death that the land gods offer to most of the lesser divinities in Theoma.
To the Risky
Similar shrines are occasionally erected to people who regularly take long voyages while they're still alive, in which case prayers for safe return are their made at the shrine. The suicidal reputation that expeditions to Hostile Theomes have likewise sometimes results in those being prepended by building shrines, though the stigma on suicidal ventures means that this is more common for the second expedition to a hostile theome which an individual undertakes. One trip to gain something from a hostile theome is suicidal; two trips to gain something from a hostile theome is heroic.
To the Blessed
Some geomancers seek out empowerments to share with others. While this requires a land god's support to grant real power to, the result is a third category of personal shrine whereby shrines dedicated to some individual geomancers return magical effects when prayed to. Although access to these shrines is often initially given only to specific beneficiaries, if one of these shrines survives for a long time it tends to slowly become a community pillar which attracts a great deal of attention.
To the Cursed
The rarest category of personal shrine is erected by people who believe that Fate is against someone they love. These are typically erected in secret rather than placed in pantheon rooms, and powerful necromantic enchantments are used to conceal their existence from the land gods. Shrines to the cursed provide a fatebreaker beacon, also known as an anti-beacon, which preserves and empowers the will of the individual to whom the shrine is dedicated, so that the land gods will not be able to predict and manipulate them. Fatebreaker beacons are a kind of necromantic construct which deeply upset most of the land gods.
This is an interesting concept :D I'm intrigued by the wider cultural implications. Can people take some kind of energy from being prayed to? Or is it more a case of praying "for", with the prayers made to the Land gods to grant something to the person to which the shrine is dedicated? Does it bring prestige for someone to be included in a lot of shrines? Is it something they're looking for? And conversely, would it be bad for someone not to have any/a lot of shrine made for them?
A lot of these people call it "pray for" (as in "I'm praying for your safety"), but it would be more accurate to say "pray to". There's no energy to be taken from being prayed to, but rather prayers interface with the weave of Fate that binds all the setting. Whenever people pray to each other in this setting, they're binding their Fates together with each other. The influences that touch one Fate start to touch the others' Fates. This is the most basic and universal kind of "geomancy" (earth magic), which is what the magic of Fate is called in the setting. Many people in the setting do think that they're just praying to the land gods. Such people may scoff outright at the conceit that ordinary immortals are 'lesser divinities'. That is however is a common misconception; the land gods are vastly better at manipulating Fate, but Fate does indeed shift for everyone in the setting, just a little bit. It's possible to change Fate by force of will, and love is a powerful bond that helps bring people home safe from dangerous journeys. Being included in a lot of shrines means that a lot of people consider your Fate to be deeply relevant to their own! I imagine this must sometimes happen to people who are deemed great heroes. If a hero on Theoma is worshipped in many Pantheon rooms, that means that they share Fate influences with many people. It would definitely be prestigious, but from a mystical perspective I'm not sure it would be a good thing. I think it might pull down on the hero by weaving their Fate with a great many ordinary Fates. (Note that Fatebreaker shrines would help with this problem!) Having no shrines dedicated to you is too normal to be a bad thing. A few people take all of this super-seriously and stuff art into their Pantheon Room representing all their friends and relatives so that everyone they care about will be Fate-bonded, but most of the time these shrines are built singly in grief or worry.
