i believe it was a goblin, however i didnt so much kill him as incapacitate him only to have him die of his injuries whilst i was interrogating him ~ my paladin didnt speak goblin, and the DM didnt know if goblins spoke Common, i think he just expecting me to kill the goblin and take its stuff, rather than try and find out where i was.. (i had woken up in a cell in a dungeon with no knowledge how i got there)
