Oh boy... what to start with?
1- I'm sure I'll get scolded by a mod to say this, but you should edit your first post instead of posting three consecutives posts (Called triple-posting, which is forbidden).
2- If you would like to join Nocturu, you must join it In-game. If you don't know how, it's written at the bottom of the first post.
3- In AQ, there's no such war between Good/Evil and Chaos. Players there are either Good or Evil, Chaotic or United, or both Chaotic Good and so on. However, it is true that in AQWorlds, there's the Good & Evil Alliance to destroy Chaos. However, what happens in AQWorlds is of no concern to Nocturu, as we do not have an interest in this game for now, unless AE decides to implant the Elemental Clans in AQWorlds. If you encountered a clan named Nocturu in AQWorlds, then it's a false one or a fan-made, but it is surely not an official clan.
4- Like I said, Nocturu isn't part/interested in other games except AQ, since it's the game in which Nocturu and the other Elemental Clans were created, so giving links to AQWorlds or MQ characters is somewhat useless. However, we did had a place where we recorded the Nocturans' characters of all games. However, it happened some time before everything went inactive that some of us were hanging out together to play AQWorlds... but that's history...
Well, I'll quit my rambling (probably due because I haven't spoken much lately). Just take the second part (in bold) seriously. As for the other parts, take them lightly, that just ramblings of an old Nocturan.
