AN94(4)AN-94||:Can you keep up, AR-15? +I can sense your pace slowing down. Is something the matter? AN94(4);AR15Mod(2)ST AR-15||:No, it's just that this place is getting darker and darker... I'm adjusting my night vision optics' parameters... AN94(0)AN-94;AR15Mod(2)||:Understood. I'll slow down and wait for you. +Still, AR-15... have you noticed? +The passage here is different from the outside. AN94(0);AR15Mod(0)ST AR-15||:Is it a matter of the construction materials? +It just feels a little different to the touch. AN94(0)AN-94;AR15Mod(0)||:This sector ought to be nothing but ancient architecture. It shouldn't be renovated, unlike the outside. +It's very likely that this deeper portion might have been preserved as a relic, and I found a lot of hidden doors that are only big enough to admit one person... +I've already recorded the positions of those hidden doors we passed. We might be able to use them in our retreat. AN94(0);AR15Mod(0)ST AR-15||:I've been making a note of them myself. According to the parts of the map that we've already explored, it's very likely that these hidden doors are all interlinked, forming a network of secret passages. +When you think about it, this place isn't just a maze, it's practically an anthill... Are you sure those passages won't collapse on us? AN94(0)AN-94;AR15Mod(0)||:They won't. They may be old, but their construction is solid. They were built using techniques we hardly see nowadays. +I can't see any reason why they would collapse, barring an earthquake or a large explosion from below. AN94(0);AR15Mod(0)ST AR-15||:...Alright then, let's hope so. +Hopefully things won't get so bad that we'll have to duck into these filthy hidden passages.
