Relations with the Kingdom of Orisaar are bad, due to Orit prejudice against the Canidaur, who are not permitted in the lands or navigable waters of that kingdom. Both adhere to The Pandect, though the Regency of Canidium is not an official signatory. As such, those legal provisions exist for people of Orisaarland within their lands, but not vice-versa. Also, Canidaur culture is nascent and highly inclusive. They are modern individualists, whereas the Sunsteda Bay Islands are home to a very clannish and culturally traditional people. On nearly every level, they clash.
The Military Republic of Altonbrun is a useful trading partner and a spiritual ally. Canidaur are welcomed in the Krokesteppe. Altonians are at worst distrustful or boring, which is most of the time. They tend to laugh at canid culture, which is no trouble.
The Order of the Crystal Sword is always sizing up which kingdom might be the first to attempt a war of extermination. The Mashayan Dominion is regarded as an unlikely candidate. Although Mashaya have insurmountable religious differences and a historical claim on The Montaignes (once known by the name Al Safas), it is believed by the Order that the Zerzuran Wordbearers aren't a threat outside the badlands. Since Mashaya are generally accepting and not viewed as a credible threat, they are generally liked.
The Kingdom of Orisaar is strictly opposed to "the Canidaur menace". As neighbors with a powerful navy and strong economic relations with the Military Republic of Altonbrun, Orit are regarded as a primary concern. The forest and plains at the northern foot of The Montaignes are a no-mans' land as a result of this tension. Their foothold at Rantaan allows Orisaarland
to project its power inland, and it remains a grave concern. Beyond the
insurmountable diplomatic, economic, religious, and racial concerns, Orit and canid characters could not be less compatible. While Canidaur are open-countenanced, enthusiastic, and trusting, the folk of Sunset Sound can come off as scowling traditionalists.
The Reign of Eld in Orchalannon is hesitantly friendly. They share certain cultural touchstones, but lack a genuine connection. However, Athosian wanderers sent west have often arrived in Buckstadt, leading to more familiarity. The Athos Highlands are regarded as a kingdom that would be wonderful to visit, but not for too long. There is much distrust of the court sorceress Maerlyn D'Ambrosio and her tightened grip of domestic affairs.
The State of Cerentuin, were they in the fullness of their sovereign power, would surely have moved to destroy Prima Canidia long ago. It is seen as lucky that they have been reduced to their present state of vassalage and ruin. It is not known if any Cerentians have ever met a Canidaur, but there is not much need to ask what they would think.
Serzy Montaigne maintains her house's shares in certain companies operating within the Kingdom of Viltmank, and remains an account holder in good standing at the royal bank. Relations with Viltfolk are as good as could be expected, but there is a rivalry between her and Ingrid that has colored some canid perceptions of Viltmank. Further, the highly fashionable Viltfolk often see canid neoclassical Armorcian revival attempts as bumbling and oafish, leading Prima Canidia to be constantly looking for new ideas in order to please them.
The Grand Duchy of Breccia are generally seen as a kingdom of Bad Humans; Canidaur emissaries have nearly caused diplomatic incidents after choking back the urge to bark. Perhaps they smell wrong. Nobody is quite sure, but Breclanders are rarely made to feel welcome in The Montaignes.
The Tamar Towpath Cartel is difficult. Canidaur travelers and traders love to visit Kurzmarch Ford and gain nearly effortless access to the downstream markets. However, the cartel are too inconsistent, inscrutable, and unscrupulous for canid tastes. Criminality and exploitation run counter to their values.
