It seems clear to me: http://paizo.com/threads/rzs2q434?Golgotha-Settlement-Charter#19 that Golgotha was born separately from Pax Gaming <--- which is not really a "Guild".
They are allied with Aeternum now and share a website. What Ally would not want space on that site if offered? Why is it wrong to plan ahead in the matter of nation states?
The Land Rush was poorly worked. There is no reason to destroy so much work because of solidarity in websites, prefixes, and alliance.
This is a case that is clearly strange, partly because things were not spelled out very well. Very important things.
They should not be considered in the class of "Mega Guilds" that are a concern. They are an asset to the community in their diversity. They were and actually are separate "guilds".
