The Great Fissure (quest)

Objectives
Ranger Captain Venn'ren at Falcon Watch wants you to slay 8 Stonescythe Whelps and 3 Stonescythe Alphas at the Great Fissure, east of Falcon Watch.
 * Stonescythe Whelp slain (8)
 * Stonescythe Alpha slain (3)

Description
We're dangerously close to becoming fenced in by Alliance forces. With the influx of sin'dorei pilgrims from Azeroth, we must establish a route that's safe from our enemies' prying eyes.

I've given it some thought and have arrived at a solution. We're to establish a secret path through the Great Fissure.

Yes, even though the area is crawling with brutal rock flayers, they are merely beasts and can be taught to fear us. I want you to go and kill a good number of them. They shall learn fear.

Rewards
You will receive:
 * 10050 XP (or at level 70)
 * +250 reputation with Silvermoon City

Progress
You've returned. Is the task done?

Completion
Good job,. That should teach the rock flayers to stay far away from us.

Progression

 * 1) Falcon Watch (quest) or Falcon Watch (blood elves)
 * 2) The Great Fissure (quest)
 * 3) Marking the Path
