im assuming you’re talking about vmv?

because, yes! you absolutely can design your ocs to fit into vmv! i’ve incorporated a lot of creations from larger creators in the utmv fandom - such as popular shipkids, au characters, ect. - if you want to create your characters in vmv, absolutely feel free to!!!

((also, i’m aware theres a ton of vmv species to pick from - check out @vampire-mythoverse - and if you’re on desktop, } here’s { a page from the blog that lists all the species and links to their known posts! feel free to ask @vampire-mythoverse about any of the species if you find info lacking or if you want to clarify anything!))

also, it depends! only angels, fallen angels, and demons can cross the planes - limbo demons and risen cannot, and none of the Terran species are able to traverse the planes.

there are three planes, Angaea, Cirxia, and Terra, and entry to them is conditional.

entry to Angaea requires a certain level of “holiness”, which is the magic of angels and which only angels are capable of possessing - meaning only angels are able enter Angaea.

-

This changes once an angel falls; because when an angel falls, their “holiness” is retracted just below the requirement, and they cannot enter Angaea because they don’t reach the magic requirement. angels fall to Terra after being forcefully rejected from Angaea from having their holiness retracted. and even then as they live on Terra, they gradually lose their holiness over time, either using it up or attempting to keep it stagnant. it will always end up slipping away due to being around magic that isn’t like their own original magic, or by indulging in one of the seven main sins of demons and stirring up miasma (the magic of demons), but if an angel so desperately keeps themself latched on to one last scrap of holiness, they can keep themselves an “angel”, even fallen.

-

when an angel loses the last of their holiness, they transform into limbo “demons” - not really demons, but not really angels anymore either. they fall farther than what they originally did, and resemble the opposite of who they used to be. ((limbo demons lose the ability to traverse the planes.))

-

entry to Cirxia isn’t quite as complicated. both angels and demons can do it easily, using their respective magic (for angels, it’s holiness - for demons, it’s “miasma“). demons may “ascend” to Terra using their miasma (which detracts from their overall supply, which they have to keep replenished themselves), and demons may “descend” into Cirxia.

-

Cirxia is split into nine circles, each of them stacked on top of each other with walkways between them like a spring. each circle is designated to a certain sin, and demons can only descend as far as their sin’s circle. lust demons can only descend to their circle, while pride demons can descend to all the circles including their own, since they’re at the very bottom (barring the despondence circle, of which there are no natural demons).

angels can only descend to the top of Cirxia, the limbo circle (which also has no natural demons), where all mortal souls rejected from Angaea go after they die. from limbo, the rest of the circles are able to be accessed through the spiral walkways.

the order of circles from top to bottom is this:

((limbo, lust, gluttony, greed, sloth, wrath, envy, pride, and despondence))

limbo and despondence, the very top and very bottom of Cirxia, have no natural demons of their sin. limbo is for rejected mortal souls and despondence is encased in ice.

-

entry to Terra is the easiest among the three planes. it requires either holiness or miasma, but since visitors from the other planes already have that, it’s all set up fine and dandy for them. there’s also no set or limited entry points (like in Cirxia), and no magical requirement (like in Angaea) to enter Terra. any angel or demon who wishes to visit Terra can do so wherever they like.

-

if they don’t know Terra very well, though, it’s very likely they’ll end up falling into the oceans if they’ve never ascended before and have no one to guide them

Angaea and Cirxia have no natural water, no natural plant life, and no natural animals, by the way. Terra is the only plane that has those and a variation within its species. Terra is weird but also really cool.

-

Also I’ve mentioned this throughout the post, but when mortals die, their souls can choose to try for Angaea, go straight to Cirxia’s Limbo, or roam on Terra for the rest of their undead lives, never really seeing or feeling without anything to give them form. rejects from Angaea are forced to go to Cirxia, while those who choose to stay on Terra can never go to either.

Those who make it into Angaea are called Flares, and they roam around the plane, never able to leave it.

Those who roam Terra are called Spirits, and they roam around the plane, never able to leave it.

Those who choose to go/are sent to Cirxia are called Shades, and they roam the limbo circle. They are sources of miasma, and often enough, demons will consume the shades to replenish their own supply of magic.
