"But wild beasts of the desert shall be there' and their houses shall be full of doleful creatures; and owls shall dwell there, and satyrs shall dance there." - Isaiah 13: 21
Not really the classical Greek depiction of a satyr, or the Narnian Mr. Tumnus that C.S. Lewis wrote of. I've read that satyr was a mistranslated from the word "Se'ir" or "Se'ar" which means hairy one, and was a reference to wild goats who dwelt in the ruins.
But for gaming sake this is a creature that is essential to the Sword & Sandal genre!

Satyrs (or fauns) inhabit only sylvan woodlands. They are interested primarily only in sport - frolicking, piping, chasing wood nymphs, etc. They resent intrusion, however, and will drive away any creature which offends them. They can sometimes be lured/bribed with superior wine.
A satyr normally attacks by butting with it's two sharp horns. They will occasionally (20%) make use of magical weapons. It is quite likely that a satyr will first play a tune on his pipes, an instrument only a satry can properly employ. By means of these pipes the satyr can charm, sleep or cause fear in all within a 6" hearing radius unless they save versus magic.
Only 1 satyr per band is likely to have pipes. If comely females are in the ground the piping will be to charm, if the intruder is relatively inoffensive the piping will be to sleep (and choice items will be stolen from the sleeper), but if the party is powerful the piping will be to cause fear. Any creature which saves versus any form of piping is not affected by additional music from the same pipes.
Satyrs are very silent and have keen senses. They are surprised only on a 1, and they can blend with foliage so as to be 90% undetectable to creatures not able to see hidden or invisible things.
These creatures have their own tongue and are also able to speak elvish (understandable only to sylvan elves) and the common speech. Satyrs dwelling near centaurs re 80% likely to be friendly with the latter, cooperating with them and speaking their language.
Description: The skin of the upper body of a satyr is tan to light brown, it's hair elsewhere being medium brown, reddish brown, or dark brown. Horns and hooves are black.
