Forces of Nature: Hippogryphs

Objectives
Use Tessina's Whistle to rally 10 Frayfeather Hippogryphs. Provided item:
 * Hippogryphs Rallied (10)
 * Tessina's Hippogryph Call

Description
Hippogryphs are majestic creatures. Some say they were created by Cenarius himself as a gift for the night elves. They're wary of other races, but they're intelligent enough to recognize a friend of a friend.

I need more hippogryphs here so we can begin training some of our newer archers to ride them. Take the whistle again and rally the Frayfeather hippogyphs [sic] in the grove just south of the Tower of Estulan.

Completion
A properly trained squadron of hippogryph riders can take on nearly any opposing force. Feathermoon Stronghold will be much safer with these noble beasts on our side.
