1 Kyros: Okay, I'll try to teleport the others here.
2 SFX: Flash!
3 {scene change: the tunnels under the Orcrift Mountains}
3 Lambert: Alvissa! How?
3 Alvissa: We teleported. Look out, you're in imminent danger from fire!
4 Lambert: Well now we are! You brought Kyros!

Now that Kyros is providing light, you can see how dark it actually was in the tunnels before.

Yes, I know the "dark" frame looks brighter than some parts of the lit frame, but that's because your eyes have adapted.
