Portents of a Beacon III

Again, the vision begins focused on the beacon.  The glass orb with water running down the sides.  This time, however, it is different.  It is seen not in the prime material plane, as in the other visions.  Instead, it appears in the Feywild.  Adjacent to a beautiful, reflective lake.  In the distance behind the beacon, an army battles an unseen threat.  Soldiers scream and dive out of the way as a large black dragon soars overhead, blasting the army with acid.  It turns around for another pass, then seems to change its mind.  It flies directly towards the beacon, crashing into it headfirst, and shattering the orb as it tumbles into the nearby lake.
At first, all is still.  The fighting has ceased.  All combatants staring, dumbly, at what was once the beacon.  Then, the true change begins.  A rift is created, and from the opening spews forth a towering geyser of flame.  It roars up into the sky, and the light is blinding.  As the initial flash dies down and the vision refocuses, it is clear the entire forest is on fire.  Elementals spew forth from the open vortex, eagerly consuming the nearby wood to engorge themselves. 
Suddenly, the vision shifts.  The beacon again?  No.  A different beacon.  This one adjacent to the River Styx.  The beacon is pulsing, waves of energy spewing forth in all directions.  A dwarf trundles up to it, visibly angry, and slams an axe into the beacon.  It shatters, and there is peace.  For a moment.  Just as the dwarf turns away, an Orc appears in the space left behind.  Then another.  And another.  And then several hundred more.  They gaze around, confused, before charging towards the nearby settlement of Zargos.
It shifts again.  The Prime Material Plane, now, right by Mirror Lake.  The same one the crew saw on their way to Stasterry.  Lenora is absent this time, but Bosgosho is still there, and an army of drow behind him.  He holds Dave, the eyeball pendant, up against the beacon.  The waters turn blood red, and then the eye appears within the beacon itself.  It speaks:

Hi, I'm Dave!

This one does not shatter.  Instead, the vision shifts again.  A primordial soup is twisting and churning, elements changing and materials shifting about with such frequency as to be completely incoherent.  A nearby house becomes a duck.  Then a goat.  Then another beacon.  Dave is in this one too, shouting it's greeting to the nearby Slaad.  One responds: "Hi, Dave!  I'm Bruzar!" As he finishes speaking, his head explodes. 
It shifts again.  The woman in a glass coffin suspended in the center of Sigil stirs, then awakens.  Her eyes are wild with fear, but she quickly straightens them.  It takes visible effort; a couple minutes of deep breathing before she can make herself smile.  She knocks on the glass, and the whole city hears:

Hello, down there!  Can someone get me out of this thing?
