Location: The Village of Lasler
Level: 10-15
Enter Alyria from the exit of Lasler Canyon.
Note: apparently you need to bribe the troll to be able to get the mark, and not have killed him before. As of 03/04/11 I was able to obtain this mark before lvl 15 (since you get ported out at 15) I killed the Troll twice.
