This is the list of the bestiary we have.
Add more by posting them in this topic.

1. Zombie - Undead - Undead creatures animated by the Dark Elements.
2. Stalfos - Undead - Warrior Skeletons that mainly use swords and shields. It's rare to fight one that does not wield a Sword and Shield.
3. Medusa - As opposed to the original 3 sisters of lore, treat the Medusa as a race. Although scarce, they act as rogues in major population centers, paralyzing anyone who would discover their true nature.
4. Spider Eater - Giant wasps - They are often used as mounts by goblins. They feed primarily on giant spiders. They lay their eggs in the carcasses of the dead.
   The ones that are goblin mounts have had their wings removed to keep them from running away.
5. Wolf - Animal - A wild wolf that attacks anything outside it's pack. Usually they appear in packs.
6. Chimera - Myth Animal - A Mythological Creature that is said to be comprised of several different animals.
7. Hydra - Aqua Demon - An aqua monster that live in the ocean. Agressive. They generally have 3 snakelike heads.
8. Giant Snakes - Animal - Giant snakes, some have poisonous bites. Aggressive creatures, best to be avoided.

Here's the way you can post them. Their name, their race if any and then a description of some sort.

Here's a few ideas from games both of the Video sort, and the other associated tid-bits.

1. Spider Eater (D&D 3rd Ed.) - Giant wasps, often used as mounts by goblins, that feed primarily on giant spiders. They lay their eggs in the carcasses of the dead.

2. Medusa - As opposed to the original 3 sisters of lore, treat the Medusa as a race. Although scarce, they act as rogues in major population centers, paralyzing anyone who would discover their true nature.

(I'll add as they come to me...)

here's one. (about time, eh?) ^.^;

1. Hell Raves- Undead- A grim reaper of sorts. A cloaked,red-eyed, skeleton that carries a giant scythe. Can phase though any surface as a sneak attack. Uses a high pitched scream to stun it's opponents in fear.

I'll throw in a few more ideas later. *shot*

I know it's not exactly what one would call original, but for simplicity's sake why not just take a copy of the AD&D Monstrous Manual (2nd or, heaven forbid, 3rd ed would do) and modify those to your liking. Throw out what wouldn't really fit the setting (what IS the setting anyways?) and keep those which would fit it.
