You should have acted. They're already here.
The Elder scrolls told of their return.
Their defeat was merely a delay.
From the time after Oblivion opened.
When the sons of Skyrim would spill their own blood.
But no one wanted to believe. Believe they even existed.
And when the truth finally dawns, it dawns in fire.
But there is one they fear.
In their tongue, he is Dovahkiin - Dragonborn!
Dawnguard
We can see Dawn mentioned twice in the seventh line.
Dragonborn
The last word in the last line.
Oblivion is mentioned and DLC has sent us to both the Soul Cairn and Apocrytha.
This is what I got out of it, what crazy predictions can YOU make out of this?
