The Lunar Republic Gaming is a late server that it was actually the one who made Slender Fortress on February 8, 2013 and then publicly released for all servers on October 21st, 2013. It was created by Kit o' Rifty.
It was closed and opened a new group here: http://steamcommunity.com/groups/CelestialGamingTF2
But on March 21 2016, the owner had given up on Celestial Gaming TF2 and had been shut down forever, because the owner was having a depression about something.
