No.
Nataria is in agreement with Xyainbor's representative. We can see no reason for the destruction of trans-universal technology, or its reduction in application. We have allies in other universes, and close ties, as well as enemies, and cutting them off could have disasterous consequences.
In addition, good sirs, there is already a considerable exploration being enacted at this very moment, primarily in the South East corner. Expansion has never been greater, there is no need to provide an insentive to this travel in the form of limiting us to this universe alone.
Our borbers our now, if not safe, becoming so. We have ships that can relocate to any part of the empire in but a few minutes, powerfull border stations being made by NovaCorp which if spread around the borders as they where intended would serve the purpose of protecting them well.
In addition, I would wish to inquire which threat we are keeping out from our universe by not having trans-universal technology? It is not our technology that the enemy will use to get in, but their own. And which threat do we fear from the outside so much that we would wish to wall ourselves out completely?
What, for example, is the danger of having a trans-universal portal to Ayenee?
