Oh is that Haven? Nevermind it's nothing.
But seriously, you need to think and do something NGD. I don't think Ra to Haven is possible because many people who play there, are the regional audience and they wouldn't want to be sent to another server leaving behind friends and communities they formed over years of playing. Merging Valhalla and Haven?.. Hm I don't know, I personally think Gamigo sucks with terrible mismanagement and you'd be bound by contractual obligations and such I suppose.
Adrian, I invite you(the irony) to visit Haven as a dev, spend some minutes with the players there, talk to them and assess the situation for yourself. You won't find (m)any Syrtis to talk to in most cases but still Ignis/Alsius are available, you could possibly get a clearer picture of the state the server is in. People have stuck by this game for years with ridiculously low population and stuff, that must mean something, to you, the game and community itself.
And with anniversary now, it's a good chance to get to talk to people as many (hopefully)could be online for the event. Give it a shot.
