Ah, but you lack the nobles to replace Aurvandil, don't you? With them you might be a true bloc. Without them you're likely to be eclipsed by the Veinsormoot, unless you are able to step up your recruitment and retention dramatically.
Indeed. With current the current trend in gains of Nobles, by the time Madina has enough Nobles to recolonize the area, it is likely Barca will already be big enough (especially with aid from Terran and D'Hara) to spoil any possible colony attempt if they want.
