Goblins
Goblins are evil. That means you can kill them with no remorse.
They are fun and easy to kill. Plus they are short, have low hit-dice and are ugly. Attack away adventurers! Goblins are the low-hanging fruit of the experience point orchard!
Unified Setting Description
Goblins are pirates. They have created a gunpowder-like substance called boom jelly. Their warships mount actual cannon, a feat no other race has equaled on land or sea. Boom jelly is also used in the matchlock pistols carried by pirate raiders. Boom jelly requires an ingredient found only on their home islands.
The gunpowder used by the Lawless Human Cities is considered a piss-poor substitute.
