following the above train of thought...
naturally, creatures can be added to or subtratcted from any category as necessary, creatures not yet on this list can be added to it, and creatures can be in more than one category. i'd appreciate your input!
Wicked:
Most fey are playful or mischievous, but these are just plain nasty. They get their kicks by breaking bones and smashing skulls.
Paraku ola'i, springheel, quickling, bramble, forlarren
Aquatic:
These fey inhabit the waterways, oceans, rivers, and seas of your campaign world. Some are good, some are evil, and some don't bother with such labels.

Servants:
These fey exist to help other fey, to protect nature, or to maintain natural balances.

Tricksters:
These fey are a little more than just playful, and love a good prank at the expense of others, but they are not intentionally sadistic. Some simply just love doing their own thing, and are not concerned with how it affects others.

Friendly:
These fey are kindhearted folk, and are often helpful to other people.
