Ah, yes. The light at the end of the tunnel is an oncoming ~~train~~ Balrog.

I keep reminding myself that even to get to the post-scarcity utopia that is TNG, they had to go through a second US Civil War, the Eugenics Wars, 27 years of WWIII, and years of being subservient to space elves. It'll get worse before it gets better.

At first I thought this was the hallway from the Maul/Qi Gon Jin fight.

Still works.
