it seemst hat perhaps the Pantheon knows about Ultera and doesn't want us fiddling with it either. the raid spawns a tthe spires before thier final completion seem to be tied to the deities. Lavastorm was reported to spawn a 'Champion of Flame' that has some kind of zonewide emote upon spawning, and LP is reported to have apparently had a Champion of Hate. unfortunately thier zw emote isn't logged, so we'll have to wait for another one and hopefully someone will remember/ copy paste it so we can know what it is they do.
maybe Ultera is the source of all teleportation, and while the Gods who apparently recharged the 'Combine' spires can tap into it/access it without [Removed for Content] off the inhabitants (or as the case maybe, control the inhabitants), the Quellthulians are deliberatly punching holes in it for thier spires, which is why the Ulterians are fighting back.
