Poe:
The scan data from Snap's reconnaissance flight confirms Finn's report.

Snap:
They've somehow created a hyper lightspeed weapon built within the planet itself.

Brance:
A laser cannon?

Snap:
We're not sure how to describe a weapon of this scale.

Major Ematt:
It's another Death Star.

Poe:
I wish that were the case, Major. [Poe controls a holographic display showing the Death Star.] This was the Death Star... [presses a button that scales the Death Star against a colossally large Starkiller Base] ... and this is Starkiller Base.

Han:
So it's big.

Admiral Ackbar:
How is it possible to power a weapon of that size?

Finn:
It uses the power of the sun. As the weapon is charged, the sun is drained until it disappears.
