Nephilim aren’t human. They aren’t even human-like. They are Aristotelean creatures born from the fluctuations of mystical fields. When the mystical field grows big enough, out pops a Nephilim, sort of like magic-focused muon out of a super collider. Except even a sentient mystical field of pure force doesn’t exist for long. It needs a vessel. Luckily, the planet is crawling with walking, talking fleshy meatbags.
The fleshy meatbag solution works only until the meatbag wears out and dies. Sure, the Nephilim can keep it going for far beyond its sell-by date, but meatbags are ultimately made of meat, and they wear out. Theoretically a Nephilim can surf meatbags like a sort of meatbag slurry but that’s not always possible. The Nephilim needs to go somewhere while it waits for the next meatbag to come along. The solution is a stasis. The Nephilim binds itself to this object and, when its meatbag wears out, it pops into the stasis like a mystical freezer and it waits for the mystical fields of its particular kind to rise enough so it can pop out again long enough to take over a new meatbag until that one wears out. Rinse and repeat.
Stasis rules are simple:
A stasis is an Aspect.
The stasis aspect may be invoked to make the Nephilim’s life incredibly complicated.
The stasis should reflect the character’s first incarnation.
The stasis should make sense for the character and the game.
The stasis should be able to survive the millennia in a passably logical manner.
The stasis should also have a bit of fun color.
The stasis may be destroyed.
Should a Nephilim’s Simulacrum die before the Nephilim replaces its stasis, the Nephilim will die. The stasis may be replaced via sufficiently interesting ritual magic using the collision of Orichalka and Ka, called litharge.
When a Nephilim incarnates, it should be somewhere that makes sense. Since Nephilim have a short duration once they leave their stasis, they are not going to travel the globe to find themselves a meatbag. They will incarnate in the body of the PC where the game is set. If the game is set in a major metropolitan area, the stasis could be in a museum or a private collection. Or buried underground. Or just unearthed from a famous dig and is now sitting in a university lab. It probably doesn’t make sense for the stasis to be an ancient Chinese military rampart if the game is set in Rome. But an ancient Chinese vase from Beijing would make sense in Rome — if it was recently stolen in a heist and now being sold on the black market!
Elijah the Moon Serpent, who lived during the reign of Ahkenaten and worshiped the great Sun Disc and learned the way of the Solar Ka has the stasis of a small scarab with the Aten disc. And the stasis is currently in the Egyptian collection in a local museum in a dusty corner where no one looks at it. It was buried since Early Christian times, but now our friend the Moon Serpent is free to go take over a curator and his first order of business is figuring out how to swipe the stasis…
