[The way the black stone surfaces have been melted and cracked and the pillars scattered as if knocked over by a careless hand makes it hard to picture exactly how they'd been set up, but it's not a totally alien arrangement. Lots of right angles, maybe not quite so grid-focused as a city with a layout planned on Earth.]

Give it time. Populations tend to rebound and they'll recolonize any ruins that don't obviously harm them to venture into. [this is absolutely not guaranteed in Velgarth, where there are still magic-irradiated regions that warp life, especially unborn life.] Things will be different. But eventually hardly anyone will think of all that was lost and be haunted by it. It will just be the world.

[Yep. Nagito's had something to do with this Tragedy that's not just 'it disrupted his life and killed a lot of people in his orbit'. The best case is that he'd had a chance to stop it and failed. She's not going to bet on that. Need, of course, has had something to do with the Cataclysm, though she doesn't hold herself responsible, exactly.]

The Cataclysm fucked things up to the point where after a couple of thousand years it started to echo. I'm not going into why, it's complicated. I'm here because I was one of the ones trying to stop it.
