I guess we will be able to trade with IC along with the rest of Liberty once we get the rephacks removed to reflect our diplomacy. Not much use in having RP permission to land in Liberty if we are blocked from landing there by the game...
I'm not sure what you mean by "look like a black paper", but we already associate with the Hessians - who are actually very similar lore-wise.
As said by Jarl, inRP we are continuing the relationship from many VF characters with the Mollys. My own character is actually an old member of the PPB who worked with the Mollys before coming to Rheinland, so another link to the faction can be found there.
ooRP, it's a bit more interesting to have somewhere else to go, since everywhere (unlawful) in Rheinland is pretty open to us already, and fills a perceived gap in the 'trading' world instead of jumping on the Blood Diamonds bandwagon with the Unioners.
We may be small, but that doesn't mean we can't spread our wings a bit for a (hopefully soon to come) time when we have a few more members.
