Need a character background written up?

[Great Dragon]

@Falcos:
Without going and getting the old Books, this is what I can recall about Wujen.

Kara tur is 2e, IiRC, so maybe here is where they first appeared?

While compairing the Wujen to a Wizard isn't completely wrong, Wujen are more Elemental-based (the basic four usually don't change, with a fifth Element added: but this last one can change depending on source: Wood, Metal, or Void)
Almost like the Elemental Specialist Wizards of 3x D&D.

Wujen can also do a bit of Spirit Talking (usually still Elemental based) with the various local Spirits (Mountain, Forest, Swamp, etc); so some people view these casters as a type of Shaman.

What set the Wujen apart from other casters, is their need to creat "Agreements" with powerful (Elemental) Spirits to gain access to higher level spells, which can get very interesting when combined. Failure to abide by the agreement causes the Wujen to lose access to (At least some of) thier spells, but this is usually very DM dependant.

Some examples include:

Only being able to bath on a certain day.
Like "Every Tuesday" or "the second day of the third week of the month" (may include not being able to get soaking wet, from Rain or even falling into a river)

Must always face (Compass Direction) while eating.

Must always wear (type) and/or (color) clothing.

Can be lots of fun!
