Children of the Night
Its Halloween so its time to dust off the old horror story episode...
Anyway, I was thinking of using classic monsters for this year's All Hallow's Eve episode. The Call of Cuthulu monsters are just too bad ass to use year in year out... 
My first thought would of course be vampires...but Vamps in space...a bit overdone and how do they survive in an enviroment where the sun always shines...
Werewolves could be interesting...imagine a werewolf who lives on the moon...its a full moon every day for him...
Zombie/Ghoul...a zombie/ghoul infestation of a colony world forces the PCs to fight them off with limited phaser power and no ship overhead to give support.
Then there's the mad slasher...Wolf in the Fold II?
Anyone got any other ideas?
Arise, arise, Riders of Theoden!
Fell deed awake: fire and slaughter!
Spear shall be shaken, shields be splintered,
a sword-day, a red-day, ere the sun rises!
Ride now, ride now! Ride to Gondor!
