There is a trait for that
• Grand Grimoire (Cost: 1 point): The Hell contains
a great repository of mystical lore, as well as extensive
ritual spaces. The difficulty of all ancient sorcery
rolls within these spaces is reduced by two, and the
Essence cost by 1. Other ritual magic (or magick) in
line with the style and theme of the Hell also enjoys a
–1 difficulty reduction.
As to if you could make this by hand after the hell is completed, I'd say that it seems narrow enough in scope that it could be done with considerable effort. As those dragon remains have not even shown up on screen there is no way to know if they would be suitable for this.
This is one of the traits that I have my eye on.
Its not as cool narratively as Lord of the Land, which literally allows you to control the weather
▪
Lord of the Land (Cost: 1 point): The Hell's nat-
ural phenomena obey your will. You can make the
winds blow as you wish, calm boiling seas or bid them
part, and call down lightning during a raging storm.
But it has actual mechanical effects worth taking, while Lord of the Land is only there for style points.
If it can be acquired mechanically in play, then it might be better not to take it while statting up her inner Kingdom and roleplay for it instead. Looting someone's hoard, for example.
I suspect that a Manse would be very hard to find in the mundane world, I wager such places or something similar might exist in the Nevernever. Undoubtedly Molly would have to fight off whatever is already there.
Securing it would probably involve binding a whole bunch of evil spirits to guard the place.
Molly would literally have to live on it 24/7 to keep it.
Else she would risk doing a grocery run and coming back to find out that the Red Court have brought an army of several thousand vamps backed with Outsiders and taken the place.
Or that Nicodemus, say, has rolled up with a dozen Denarians, several score cultists and warbeasts and camped on the front lawn.
And as badass as we are, I dont think we are an Archive-tier heavyweight.
Yet.
Demonreach may border on N/A if we stat it as a manse. Passive defenses that can hold of armies of outsiders? Keeping hundreds of high power horrors safely imprisoned, with possibly something far worse at the bottom? Constructed across time? Perfect awareness of anything on itself? Able to resist two fairy ladies that made it past said defenses? Able to pick its own keeper and communicate complex information to them? A "nuke the continent" safeguard? Possibly more?
That thing would be high tier even in exalted.
Demonreach is certainly a <Background NA>.
Possibly several <Background NAs> to represent the spirit as a Familiar NA, and the island itself as a Manse NA, the auto-binding against Mab-tier entities as a <Weapon NA>, and the continent-destroying self-destruct as another <Weapon NA>.
Soo... I found something odd. In Hunter the Hunted II there are so called asset merits, including this one:
Occult Library (2- or 4-pt. Merit)
Your character owns an estimable collection of works on
arcane lore. If he has access to his library, you can lower the
difficulty of Intelligence-, Occult-, or research-related rolls
by 1 when he's attempting to solve an occult mystery or
generally learn more about the occult. Having this library
doesn't automatically mean the hunter's an occult expert, it
just means he has convenient access to some knowledge. If
you have purchased the four-point version of this Merit, your
character also has an Occult Laboratory stocked with strange
and rare ingredients he might need for his Numina rituals.
In Mage something like this is a Background and building it up to a level where it would be actually useful would be impractical with VED. But on the other hand if I'm willing to give you the preternatural power that is Unaging or Nine Lives it seems a bit arbitrary to stop at Hedge Mage's library. Also getting someone to make a wish in part or in full for your benefit is very on theme for an infernal. So all in all this is valid and so's this:
Science Laboratory (2-pt. Merit)
Your character has access to a fully stocked laboratory with
functional scientific apparatuses and research equipment.
When she has access to her laboratory, your character can
perform experiments, run tests, and collect data, and you may
lower your difficulty by 2 for relevant Investigation or Science
rolls, or lower the difficulty by 1 for other appropriate rolls (as
determined by the Storyteller) while she uses the equipment.
How your power pulls at the threads of the fate to give these things to the supplicant is not under your control, but they will have it the moment you grant the wish, even if they might not know about it at once.
Acquire a 5-dot Familiar, give them the enhancements
Spirit-Tied Pet, Spirit-Shape Companion and
Saga-Beast Virtue,(page 293-295 of the PDF) then have them make a wish for a Library. I recommend something lowpowered, or for which owning a library is thematic, along the lines of a Mouse of the Sun, a crow, an owl like in Avatar series, or a very small dragon.
Or if you're a Pratchett fan, an orangutan.
