The TW corp moved into Fade last fall as a resident with assistance from FREEE, who we later merged with. The TW corp remained in order to continue to bring new members into the game and help them along. We then lived in Dek for a while when FREEE was part of IRON, and moved back to Fade in the last couple of months.
NFC was a group of former IRON/Resident corps that decided they weren't happy with IRON anymore, tried to take over the alliance, but IRON saw it coming and said "screw you guys" and left Dek. NFC and FLA (another Dek alliance) couldn't get along, so they had a war that never really got settled, during which time Sparta moved into northern Dek to hold it for NFC.
NFC/FLA continued to not get along, and IRON was ready to reclaim their home, so they come back and wage war on NFC. Sparta starts to help NFC, but decides to remain neutral. NFC loses the war, supposedly surrenders Dek to IRON, only to jump over into Sparta, who then assumes control of the towers holding VFK and JU. IRON doesn't like this, so IRON/FLA attack Sparta.
Sparta decides that D2 isn't going to come bail them out of this mess, so they decide they don't want to be friends with them anymore, and cut a deal with Goons.
