Frozen World

It's a normal day, you know?
Well, for Eragon it seems.
He is riding on Saphira, speaking to an elf student in Vroengaurd, until time just stops.
The student stops speaking.
Saphira is still flying, and as soon as time stops, she manages to speak.
They don't understand why only they can move.
They stay like that for a while until they land.
When they land, though, nothing moves.
It's all still... and... wobbly?
No, scrunched.
Something is happening to the air around them.. like it's transforming.
And then...
What happened?
