I didn't join until the middle of TWD Northwards, so I can only relate what I saw. Basically, there was a group that formed in some of the north-western states that migrated around a lot, gained and lost characters and did cool stuff much like the show's cast. They holed up in a school for a while and my character Matt (whom my username is based off of) a US Army Captain, arrived during this period. He remained with the group for six months, acting as a head of Security and organizing a small and effective militia to defend the group, occasionally butting heads with the more pacifist members of the group. A zombie horde of a little over a thousand rolled into town without warning one day and the Captain, aided by several militiamen, evacuated the women and children while his Lieutenant and the rest of the group led the defense of the school. Hundreds upon hundreds of Walkers were slain but in the end there were too many and the school as overrun, killing most of the group of 40+ including Shelton's Lieutenant who died (along with several comrades) leveling the school to distract and trap some of the walkers while a few others escaped into the wild. Over the next few months, Matt became the leader of his own group made up of several militiamen and the old group's women and children as well as a young woman, Shan, whom he formed a romantic relationship with. Unbeknownst to this group, the rest of the main cast had also survived and formed their own group further away, in (of all places) a different school. These two groups came close to meeting and reuniting on a few occasions but fate always stepped in and prevented their interaction. Jackson, a hardened criminal and ex-security contractor arrived in the area of Matt's group with a band of raiders towards the end of the RP. Shan, the Captain's aforementioned girlfriend, left on her own to find the school group or at least evidence of their survival and was captured by a roving patrol of Jackson's who beat and attempted to rape her. Shan narrowly escaped for a brief period but was quickly discovered again by the same patrol, now short one member (By her doing) and looking for revenge. The Captain arrived then, having tracked her to the bank where the ambush took place and expertly beat down and crippled one of her surviving assailants, chasing the other into an alley and feeding him to a pack of Walkers. The Captain then (to the dual horror and satisfaction of Shan) tortured the surviving Raider for information on his group and leader, then hanged him from a light post with an American flag patch stabbed into his chest as a message/calling card. He and Shan then made their escape to a secluded area of the town just as Jackson and his raiders showed up to answer the patrol's distress call. They found the corpses of their comrades and were briefly distracted by Matt setting off some .50 caliber machine gun rounds as a diversion. The couple shortly thereafter made their escape and returned home safely with Jackson and Matthew swearing revenge/declaring war on each other.
The roleplay then died. Unless the roleplayer controlling Jackson and Jamie (one of the militiamen in Matt's group) decides to join the RP (and the new guild for that matter) it will be mentioned in passing that both died over the course of the roleplay, prior to the group moving deeper into Washington were they now reside.
Any old RPers from Northwards, feel free to correct me.
