First post on the IC is made, small stuff to intro the characters before we get into business. So going over some small details about the world first.
Everyone who can maintain a normal appearance are allowed to live in or nearby Washington DC. Whoever can't are given housing within HQ.
People are normally expected to show up around 8 am for any morning debriefings or other various assignments. However of course as seen here this isn't something that gets heavily mandated anymore thanks to the wonders of texts, emails, and very frequent delinquents like Pietro.
Like stated in the post, the Project: X-Men base is located a bit underground below the Pentagon. Using a system of security measures like eye scanners, finger scanners, ID swaps, and other things to allow access for those authorized. Since as Mystique could clearly prove, its possible to infiltrate as an unauthorized personal, and has happened in the past albeit it not very often at all.
