[[http://forum.nationstates.net/viewtopic.php?f=25&t=158138 Demon Castle Wars]] is a NationStates rp and part of Roleplay/NightkillsShit.

The roleplay is about a millenary organization of powerful demon hunters only known as the Order, led by a mysterious entity named Eclesius, whom no one has ever seen or heard. This Order sends it's elite to fight against the hordes of Hell, that have gained a foothold in the human world through the Demon Castle, a nightmarish structure from which wave after wave of demons pour out endlessly. The Order made it's existence public and requested assistance. The nations of the world have formed the Intercontinental Guard and blockaded the Demon Castle as a response. Now, the Order's elite is about to face their most dreadful challenge yet, an event that is said to be the most difficult challenge mankind will face in all of eternity...
