Price of Courage
DISCLAIMER: Your Steps and Tasks may be different
Prerequisite for this quest is the Goblin Incursion quest.
Talk to Maggie at the tavern in Ludlow. She will tell you of the troubles of young Trini Piper, whose parents were killed by Goblins at an early age. (She was raised by Jezzy Piper.) Talk to Trini, then Jezzy, and the latter will ask you to kill the three goblin servants of Grilk: a ratmaker, a footscratcher, and a bonescraper. (They con to about lvl 10, while Grilk himself is a 13.)
They can all be found just south of Tepok's Mine. It is a goblin convention there (up to a dozen conning up to lvl 13), so bring help. As you slay each of the three servants, a Goblin Head will appear in your knapsack.
Take the three heads to Commander Jusen in the tower due east of the mine. He will give you a King's Token. Take the token to Trini, who accepts it as a legacy from her parents. Talk to Jezzy Piper, who will thank you and give you 15k experience. Then talk to Maggie, who will give you your choice of one of four magic bracers.
