The main issue with players interacting with Gallia is it's actual roleplay.
It's insular and secluded.
There are very few people in Sirius who actually have any interaction with Gallia outside of..Gallia.
Till the Gallic house wages war on Sirius (Which would be something that would actually involve everyone in the community) then it will remain as it is. This is something that is actively driving people away from the area, like myself.
