Marshal Dughan wants you to speak with Guard Thomas.
If you are concerned that the rumors of murlocs are true, then do this -- travel to the eastern Elwynn bridge and speak with Guard Thomas. He has been stationed at the bridge for the past week and will know the state of the area.
I have here a Stormwind charger that will take you to Guard Thomas. Let me know if you wish to make use of the horse.
You will also receive:
- 85 experience
- 60 (if completed at level 90)
- 250 reputation with Stormwind
