Background: The Conjurer (Nine of Stars) (Sage)
The coming of an unexpected supernatural threat; those who think of themselves as gods.
In a place where everybody lays dormant, the few who wake up consider themselves superior, even though their life is miserable and usually short. Same as the Myth of the Cave and the Buddhist tradition of Ascension, these chosen few acquire the responsibility to bring others out of the darkness, and they are quite aware that knowledge and enlightment are the right tools against it.
Class: The Philantropist (Two of Coins) (Artificer)
Charity and giving on a grand scale; those who use wealth to fight evil and sickness.
The last one from a long line of crafters, Yunjiang gave away a pleasant - even though unreal - life as a wealthy smith to fight for his people. He even lost anyone's most precious possession - his own life. And he's still willing to use all what he can craft to protect those in need.
Domain: The Enchanter (Three of Stars) (I'Cath)
Inner turmoil that comes from confusion, fear of failure, or false information.
Yunjiang comes from a place where no one knows whether they're awake or asleep. The Darklady maintains the population under a deep slumber to manipulate their dreams, and those not sleeping have to face the most terrible horrors. Confusion, false information...
Dark Gift: The Horseman
Death; disaster in the form of the loss of wealth or property, a horrible defeat, or the end of a bloodline..
Yunjiang has indeed lost many things. Whether this translates into a Dark Gift or not, and which one, is up to the Fortunes (aka the GM) to decide. I have to say, though, that Echoing Soul connects well with the fact that Yunjiang has swapped his body.
Flaw: The Artifact
The importance of some physical object that must be obtained, protected, or destroyed at all costs.
Yunjiang has had a dream, and an artifact always appears in it. It seems a very important thing, and it sheds a bright aura. Now, where does that artifact come from? He doesn't know. It could be something he makes, or something he finds and needs to understang, or even deactivate.
Ideal: The Priest (Master of Glyphs)
Enlightenment; those who follow a deity, a system of values, or a higher purpose.
No one knows about tools more than Yunjiang, and he's aware that most of them are just that - tools. The Cosmos uses tools to evolve, and in that same way it used the Dark Lords and the Domains of Dread to evolve. Each tool serves a purpose, and has limited utility, but all of them together...
