Once you have unlocked the first set of dailies at the Regrowth, you can find a group of former low-level druid trainers in Hyjal, patrolling the western side of the zone.
from top left clockwise: Gart Mistrunner (with a Treant Ally), Zen'tabra, Mardant Strongoak and Celestine of the Harvest.
One of each druid race, so at least one "familiar face" for druids that took note of their surroundings when levelling, which they even acknowledge (see end of this post)
Mardant appears to be the leader of the team, as he proclaims the beginning and end of their tour.
They start at the Sanctuary of Malorne, still each in their humanoid form:
Mardant Strongoak says: All right, troops. Look alive! Is everyone ready?
Zen'tabra says: Yeah mon. Let's get dis show on da road.
Celestine of the Harvest says: On the prowl.
Gart Mistrunner says: It's stomping time.
Mardant Strongoak says: All right team, all systems are go! It's morphin' time!
Mardant Strongoak says: Ready yourselves in 3...
Mardant Strongoak says: 2...
Mardant Strongoak says: 1..
Mardant Strongoak says: Battle forms, go!
Mardant Strongoak says: Take your positions! We are ready to roll.
Mardant transforms into a bear, Celestine into a cat and Gart into a moonkin. I think Zen'tabra is supposed to be the healer, but she uses balance spells anyway, I've never seen her turn into a tree.
They travel west and north, towards the Whistling Grove. They attack all enemies on their route (but don't worry, their corpses still are valid targets for Perfecting Your Howl) with appropriate abilities for their form, except Celestine, who just melees. She also doesn't get behind mobs, which is rather weird for a cat.
When they reach the northern end, they circle back to a cliff over northwestern Ashen Lake:
Mardant Strongoak says: Good work, druids! This area looks secure. Let's head back to base.
Mardant Strongoak says: Assume flight form in 3...
Mardant Strongoak says: 2...
Mardant Strongoak says: 1..
Mardant Strongoak says: Storm crow, go!
They fly over the Ashen Lake, circle a few times above the Sanctuary, then land at their starting positions, shifting back:
and rest for some minutes.Mardant Strongoak says: Good work, team! Take a breather and report back soon.
An additional gem is that if you talk to them on a druid character, the one corresponding to your character's race will have a short speech for you:
(Worgen) Celestine:(Tauren) Gart:<Name>, I am not surprised to see you here. I always thought you were my brightest pupil. I am honored to fight alongside you, my friend.(Night Elf) Mardant:Hello, <Name>. I heard the call to arms, so I've temporarily taken up my fighting form. You have learned all that I have to teach, so I leave you one last lesson. Fight bravely, young one, as an honored member of the Horde.(Troll) Zen'tabra:<Name>, you look well. I heard the call to arms, which is why I've left our home and come here to join the fight.
I see you have grown much since we last met. I am honored to have taught you. You are a true hero of the Allance.Otherwise they just say:Ahh <Name>, it be good to see ya once agin. Da threat to dese lands be grave, and I come to join da fight. I see ya grown in your own. Good. You mek me, an' all your tribe, proud.You come to join the fight, <class>?
An entertaining detail of that area, especially for druids, and even though they have nearly no ingame purpose (well, as I mentioned, you may find use for the corpses of their enemies) but I wish there'd be more stuff like this
(me and the gang)
For completeness' sake, here are their battle quotes:
Celestine:
Gart:What big teeth I have? Why thank you.
I've sharpened my claws just for this moment.
Begone from these lands, invader!
The very trees repel your presence!
Mardant:Taste the fury of my moonbeam!
Fire! Fire! Fire!
Zen'tabra:Enemy sighting!
If you haven't run by now, it's too late!
Team druid, attack!
It don't mattah what you do heah, ravager. Da land will heal after you be dead.
Die! Let da fires consume ya once agin.
Return to da fire from whence ya came, ya ill one.
