The Characters of El Hazard
Just some character descriptions, a pic if it's available, a Japanese sound bite (courtesy of AIC; unless I say, I don't know what they're saying) if available, and any memorable quotes. My apologies if the quotes are somewhat inaccurate; I'm working from memory here. Where applicable, I've included the alternate Japanese romaji spelling for the names in parentheses.
There are some spoilers in here! You have been warned.
The Earthers--the folks from Shinonome Koukou
Roshtarians--at least, those of or directly involved with the royal family
Priestesses of Muldoon--controllers of the elements
