The sublevels of Av-tech are much like what used to be the Archives of Metru Nui. Cluttered, dusty, and very, very dangerous. The top layer of the sublevels is full of dangerous tests that have gone wrong. These levels are patrolled by Krahli. This is were the sterile, clean part ends...The deeper you go into the sublevels the more dusty and damaged things have become. Rust has corroded most of the walkways making them about as safe as the average Skadki. These levels contain relics the pre-date the GSR. These relics have been all but forgotten. Should they stay that way remain to be seen....
