Article 1

There is a strange energy coming from a device in Atlantis that affects John on a monthly cycle, coinciding with one of the moons. John tries to ignore it, but after a few months it starts making him sick. Rodney tries to destroy the device, but it turns out it's basically a reminder for Ancients to procreate, so they deliberately made it to be indestructible.

John/Rodney, probably on AO3 but not necessarily.

Thanks!
