I can only speak for Rhidhana and not the rest of Fontan's negotiators at the time of the surrender. To her Nivemus is not a Sirion colony, but rather a homeland for the Rancaguan people cleansed of the poison of old King High Guard and his cronies. She still visits Ashforth from time-to-time to trade supplies and is hopeful that in time the northern realms will heal the old wounds and resume their ancient friendship.
Yet High Guard (same character but renamed to Monte Cristo) is the ambassador of Nivemus.
