Usurper of Cosmic Tides

Lo, beneath the vault of yon heavens rend
Where aether’s weave in twain was cruelly split
Did planes unbidden sunder, twist, and blend
And realms of mortal ken to chaos flit

A harvest grim, by blood and bane besought
Was wrought upon those cursed forbidden fields
Where shards of divinity lay broken and fraught
Cloven, yet vast puissance still they yield

What ancient seals were forged in elder days
To keep the light from touching dread’s domain
Now sunder’d lie, as horror lifts its gaze
And cursed shapes do tread where none remain

From out the yawning void did whispers seep
Of truths too eldritch for frail minds to bear
As mortals, drunk with power, rouse from sleep  
That which was never meant to linger there

O wretched man, who dares the hidden key
To realms where light doth falter, dim, and fade!  
Know thou, the aether's wounds shall never cease
And what walks now shall ruin all it surveys
