So, we know that the Facility was manifested from A's mind, right?

Well, I have a feeling 27th of March was the day Garion's raid on the original outskirts laboratory happened.

Various things such as Bloodbath and the Ordeals were manifested from Ayin's fears and traumas since the Facility was essentially built using his mind, so I feel like Shelter could have also.

Ayin and Benjamin were the only ones safe while Kali fought like hell on the outside against Garion. This mirrors how whenever someone stays inside of the shelter, other abnormalities begin to come out, which is pretty much exactly what happened during the Outskirts raid.

Also, this one isn't as much of an evidence but more cool, but the Shelter is one of the ways you can kill Gebura during her meltdown. What doesn't this work against? Binah's meltdown.

I don't think this was really intended, but I do love how 27 appears in every chamber except the Shelter from the 27th of March, which I feel like was the day everything went wrong in the original lab, where Ayin and Benjamin were the only survivors, essentially sheltered on that day.

I think even if this wasn't the intention from the developers it's just very cool how everything lines up, and I would love for this day to have some significance
