A crossword to all and to all a merry Christmas!
(Good luck with formatting! I think you'll have to copy it down onto graph paper or something.)
There's a message if you copy down all the letters that you don't use in the words. (Bonus doesn't count; you need those.)

There's the one that works. Trust me; I tried it the first time and couldn't for the life of me figure where Apophis and Dr. Jackson had run off to.
I suppose you'll want a word list, huh? Well! The demands you people make!

Anise
Anubis
Apophis
Baal
Bretak
Carter
Chaka
Colonel
Daniel
Hatak
Hathor
Jack (And NOT the one found in Jackson! Unless you can't find Jackson and then that's okay.)
Jackson
Jolinar
Jonas
Kasuf
Lantash
Linea
Loki
Oma Desala (one word; no space)
ONeill
Osiris
Ra
Ryac
Samantha
Setesh
Share
Sholvah
Tanith
Tealc
Thor
Yu

Bonus:
Find the princess. (Think a movie that came out in the late 70s, early 80s, late twentieth century, and early twenty-first century.)
Find a kind of precipatation.

I find it amusing that it worked out that Jack's by Hathor and Teal'c's by Tanith.
