I think once you get to level 25 that you should be able to make 1 territory like a colony with block protection, but only 60x60 blocks around the TGen. The outpost can be claimed as a territory for another town at any time in the town's vulnerable period. The outpost would have a portal in the TGen, but only in the TGen, The Portal can not be moved. The outpost would cost 6 times more than the normal territory and if let go it will act as a neutral territory that can not be claimed as an outpost unless another town owns it. You can not name it, it will just be called and seen as (Town's name)'s Outpost.
