All that remains now is to organise an event to celebrate this. After that we can all gauge the reactions of the various Rheinland factions (I anticipate mixed responses from both lawful and unlawful).
This has been built up over months of positive RP encounters.
If it were a situation of low-level conflict and backbiting (like the GMG and Corsairs), this would never have happened.
To my mind, it represents a real-world outcome to an issue of historical grievances.
