[@IceHeart] I'd say keep the Great Tomb of Nazarik and Momonga and Co as characters to be able to interact with in the RP, whether to fight them or otherwise. 

1. But i like the idea of a "last day of the game" guild being made to host a party for various players, who join just to go have some fun until the game ends. Then, upon being teleported to the new world into the same place, they can group up, branch out on their own, or the like to get out into the world, explore, and the like as has been mentioned before. This allows a wide range of alignments and such to be brought together, and this effectively loose alliance of players might even stick for some when they enter the new world. 

2. Though secondarily i'd say that a sort of "general purpose guild" might also be a good idea, consisting of a range of players, races, and alignments that came together just to get in-game help in general, whether it be with quests, dungeons, raids, or the like. Due to this nature of being "general purpose" and not really discriminating against the in-game race of its players, the guild has been looked down on by some, especially by those who are "racist" against the likes of the heteromorphic races. 

Though also due to this "swiss army knife" sort of organization within the guild, despite being one guild as a whole it has branched into various sub-groups located within the guild that specialize in various aspects of the came, such as "roleplayers" and "hardcore raiders" and the like. Though these smaller groups are not on the scale of full guilds made for that purpose, these smaller groups grant the overall guild a sense of variety, something that comes into play after being transported to the new world. Some might stay guild-bound due to some sense of unity or camaraderie (perhaps being part of the leadership who try to keep at least some of the guild together in the new world), some might have loyalties to their specific groups who perhaps splinter off after arriving, and some might just be average players who joined the guild and never really became attached to one small group or another within it (who might wander off on their own).

At any rate, i have late shifts at work today and tomorrow, so i won't be on at night tonight or tomorrow. But i'll keep an eye here and see if an RP comes to fruition. ;)
