Using the Warmaster Galenir part of the progression thread to get a picture of the "raiding guilds" on Shivermere...
1. <Ascendancy> 16/04/2011 [Defiant]
2. <Art of War> 17/05/2011 [Defiant]
3. <Ancient Dawn> 19/05/2011 [Guardian]
4. <Nisroc> 08/06/2011 [Guardian]
5. <NID> 12/06/2011 [Defiant]
6. <Hardcore Slayers> 20/06/2011 [Defiant]
7. <Mystical Awakening> 23/06/2011 [Defiant]
8. <Three Crowns> 27/06/2011 [Guardian]
9. <Harmless> 28/05/2011 [Defiant]
Ascendancy was disbanded. The following guilds have transfered: Art of War, Ancient Dawn, Nisroc, Mystical Awakening, Three Crowns and Harmless. That leaves:
NID and Hardcore Slayers, both of which are Defiant guilds. Not even sure whether these guilds are still on the shard.
If you look at the Prince Hylas post for decentish progress in GSB you could add Wildseven and Ordo Fidelis to the list. Wildseven and Ordo Fidelis are (I believe) both non-English speaking guilds as well.
So three Defiant guilds (one of which is a non-English speaking guild) and one (non-English speaking guild) Guardian guild left.
Is Shivermere dead or what?
