Astrous and Voidlak (Tactics)

Astrous and Voidlak are the two final bosses in the Sacred Holme. They must be defeated for a quest, and to possibly save Outhria. They are both major encounters, and incredibly tough to defeat.
Astrous and Voidlak are the most powerful Ubers of all, can you defeat them?
==Abilities==
The fight uses a mechanic where the brothers shift dimensions, after losing 5% of their maximum health.
===Plane Shift===
When either Astrous or Voidlak shifts, they will cast Ancestral Being, and then in order: From the Heavens, Almighty Capture, and Bid Farewell.

==Quotes==
===Intro===
*Tyurak Riften: Astrous and Voidlak are just ahead. It was a great shame we had to befall the protectors of the Holme.
*Garnor Azetras: We can rebuild them and breathe the essence of life back into their bodies. But we must make the duo reconsider. The future of Outhria hinges on our actions.
*Tyurak Riften: Give me a second to align the stars, and open the gate of the Starcallers.
*The gate opens, and the entrance to the Celestial Observatory is opened, leading to Astrous and Voidlak.
*Garnor Azetras: Astrous! Voidlak! I beg you, cease this at once! The world's fate is not meant to be so trivially judged!
*Astrous: If only you knew what lay beyond. The Eye of Origin, we have scryed with it, and the futures it has revealed to us call us to hasten our resolve.
*Voidlak: Altered Freedom will come to pass. The world is too dangerous as it is now. And in time, Outhria will be destroyed. It is a curse, this knowledge, but we must bear it.
*Garnor Azetras: How can you be certain of your own calculations? The Eye of Origin may be playing tricks on you!
*Tyurak Riften: Please, let us have a seating with the God Council, and prepare for what lies ahead. I know you two are resolute in your work, but the mortal champions of this planet have shown us, and many others, that this planet deserves a chance.
*Astrous: You are foolish to think the Eye is tainted. Do you not remember when we used it on other worlds, and you saw what has come to pass? Outhria is no different. We will send our response to the Makers. And this world will be judged for it.
*Voidlak: We are running out of time. The response has already been sent. But you will not delay Freedom. This world has been determined to be too unsafe for it to continue, too unsafe for it to be protected against the evil forces that lie within.
*Tyurak Riften: Champions, this is a dark hour ahead of us. We must stop them!
===Aggro===
*Astrous: You know nothing of what lies before you.
*Voidlak: A meaningless battle! It is too late to change anything!
===Plane Shift===
*Astrous: I must restore my strength.
*Voidlak: I shall return.
===Battle===
*Altered Freedom will come to pass!
*The Eye of Origin has shown us the end, why must you rush yourselves to a hastened fate?
*Outhria has experienced its final hour! We did what must be done!
===Endless Suffering===
*You will experience our ire, eternally!
===Absorb Strength===
*Our power is unlike anything you have ever faced!
===Initiating Countdown===
*Astrous: The response is halfway there.
*Voidlak: The world... it is sad to see it go.
===Molecular Separation===
*Garnor Azetras: Champion! There are five gates that are bringing in celestial essence! You must close them, quickly!
===Death Slash===
*Taste the wrath of a judged world!
===Endgame Portal===
*Reorigination shall proceed. I will always remember this final conflict.
===Wipe===
*Their tenacity and efforts, maybe we were wrong all along.
===Outro===
*Astrous: Stay your arms! Voidlak... their spirit, their will, I...
*Voidlak: Perhaps, we were wrong, brother...
*Tyurak Riften: We can still modify your response! While there is still time!
*Garnor Azetras: It is never too late to save our world.
*Astrous and Voidlak modify the response, allowing the players to send the emergency signal.
*Tyurak Riften: It is done then. 
*Tyurak sighs relief.
*Garnor Azetras: What did you see within the Eye?
*Astrous: The world coming to an undesirable end. If you truly believe it tainted, then let me show you.
*Astrous puts the memories into Garnor's mind.
*Garnor Azetras: By all that is... it cannot be.
*Tyurak Riften: What did you see, Garnor?
*Voidlak: The same as we.
*Voidlak transmits the same thoughts into Tyurak's mind.
*Tyurak Riften: This... we have to prepare.
*Astrous: We know now, that the future is not pleasant. But, you have proven to us there is a chance the planet is worth saving. I am no longer certain of the role I now play.
*Voidlak: We sensed a whisper between the two of us, the voice of the Makers, telling us to hasten our delivery of the response, but whether it was for good or for naught was our decision. We saw the world begin to turn, and that it spun in multiple directions, and all paths lead to doom.
*Astrous: Salvation would be... impossible.
*Voidlak: And that is why we did what we did. Do not make us regret the modification. We did what we thought was right, but now, that chance lies in your hands. Do what you must, but we will be watching.
*Tyurak Riften: Then we do what we shall. In the meantime, I believe the Godvault must be enhanced in all means of protection. What say you, Garnor?
*Garnor Azetras: I will send word right away. Adventurers, though you may wish to know what they truly saw... I believe it is best we keep that between us for now. But never forget what you have done for Outhria this day.
