Your trials against the Burning Blade are finished... here in the Valley. But I want you to report your findings.
Tell Gadrin of the Burning Blade, and that they have reached the Valley of Trials. Discover from him if they have yet reached Sen'jin.
Go, <name>, and be swift. I fear the evil found in the Burning Blade Coven is but the herald of a larger threat…
Hm… your report comes at a bad time. The Burning Blade is not seen here in Sen'jin, but their evil has taken seed off the coast, on the Echo Isles.
Leave the Valley of Trials and stay on the road until you come to the main Durotar north/south road. Turning right (south) will lead you to Sen'jin Village. Turn left (north) to go to Razor Hill (and ultimately Orgrimmar).
