If you complete this quest and then betray to Freeport before completing Learning from the Crystal (the eleventh quest in the Claymore Timeline, the final one in Sanctum of the Scaleborn), you will be UNABLE to finish this quest as Murrar Shar will refuse to talk to you. Completing this quest will flag you to talk to Murrar regardless of alignment.
Petitioning will NOT work as of January 2023 on Varsoon Server. The GM will tell you to betray back to finish the quest, thus potentially forcing you to buy another betrayal token or go through the betrayal process again in order to continue the Claymore Timeline.
