No longer can we allow Fyrakk to lie here peacefully, twisting himself with shadowflame and becoming a threat on par with Deathwing. We must act! It is dangerous? Yes. But not to do anything would be catastrophic.
I have ripped gronn apart with my bare claws before. Those battles were gambles, this one is not. Slaying a proto-dragon with a weapon meant for dragonslaying is obvious. It is logical. It is guaranteed.
I will not tremble before an opportunity to end this now.
Ebyssian says: Has Fyrakk always been that huge? He looks bigger than when we last fought.
Sabellian says: I have killed gronn that would dwarf this gnat twice over.
Ebyssian says: I believe he is growing more powerful as he absorbs the energy of the caldera.
Sabellian says: Then it is imperative to strike now before he grows beyond us. <Name>, you have dealt with monsters like this; you know this to be true.
Speak with Sabellian:
We cannot ignore this opportunity.
I have a perfect shot at the underside of Fyrakk's neck from this angle. It will kill him.
The Zaqali will retaliate, but you are sufficient at killing djaradin by now, I measure.
Are you ready?
What if your plan fails?
It will not. I am certain of its success.
Regardless, Fyrakk presents an immediate danger to the dragonflights and the other peoples of the world. We cannot, in good conscience, merely observe and report. We must act!
If you are worried, fear not. We have the high ground. We have cover. Protect my flank and I will save us from this monster.
I want to talk about something else.
(Quest) I am ready.
Sabellian magically holds the spear above his head and launches it at Fyrakk!
Sabellian says: The black dragonflight will never allow another shadow-spawned monstrosity to arise!
Fyrakk yells: A spear!? Do you think I am a FOOL? The djaradin would gleefully kill me if they could pierce my hide!
Fyrakk launches a blast of shadowflame at Sabellian, launching the latter away! An Erupting Shadowflame spawns in his place.
Ebyssian says: Sabellian!
Fyrakk yells: The worms tempt me to action! The shadowflame is almost mine! Do not leave the caldera. So close...
Fyrakk yells: Use the shadowflame? Yes... Yes! My new power!
Players are debuffed with:

Fend off the elemental and an in-engine cutscene plays:
Fyrakk says: THIS POWER... IS NOW... MINE!
Fyrakk gets to his feet as shadowflame bursts out of the lava around him. Ebyssian desperately pops up an earthen barrier.
Fyrakk says: RISE UP FROM YOUR SUBJUGATION, ELDERS OF THE DJARADIN!
A wave of shadowflame washes over Igira, awakening her.
Ebyssian says: Augh! -- We cannot hold here!
Ebyssian shifts to dragon form, snagging Sabellian and the champion and flies away.
Fyrakk says: Elder Igira! Do not let that child of Neltharion escape!
Igira says: Argh!
Igira launches her spear, striking Ebyssian!
Ebyssian says: Ahhhhhhh!
Ebyssian crash-lands, popping up a big smoke cloud. The champion and Sabellian look at Ebyssian. Fyrakk, assuming the dragons and champion died in the crash, flies eastward.
Fyrakk says:Primalists! Zaqali! Onward! PURGE THIS CAVERN -- AND THEN, THE DRAGON ISLES!
Sabellian says: Loamm...
A pre-rendered cutscene immediately follows:
Loamm. Elder Honeypelt walks along the northern path out of the city. She sniffs as the cavern lights up. As Fyrakk flies in to attack, Brynnsahce runs forward in an attempt to reach Honeypelt. Fyrakk unleashes a breath attack as the scene cuts to black.
