Cool! 
It won't be for a while until I achieve a lordship in Terran, I think, but who knows. 
I got a pretty warm welcome and seems like some bright minds are located in Terran *coughmoresothancaerwyncough* Haven't joined any of the guilds or religion so far, and I don't think I will join a religion. Not for Hyperion, at least.
If I had stayed in Itau, I might have seen more of Glaumorig-a-jig 
Terran will need more knights or a change in estates before we get new regions. Probably there will be a large shuffle in lordships in a month or two.
In the meantime, you should totally join a religion. Especially in Terran. The Senators of 8 regions are Triunists, and 1 is Astroist. Only 1 Senator is not officially religious. All of the Magistrates are religious. Joining a religion in Terran is an important political step, alongside joining the Véinsørmoot.
