Be warned: These charities and such push the boundaries of the terms. Where is the funding for this coming from? With limited success in conversion and whatnot within Avalonia there can't be too much revenue to support charity, and if the money isn't coming from within it's coming from outside Avalonia, namely Atensia - and that produces among the poor some loyalty to Atensia rather than Avalonia. The missionaries are warned to stop any actions of that nature funded by foreign sources and to put more careful consideration into what they do - this will be the only warning. The church construction is allowed, however.
Bear in mind that as far as organized religion goes in Avalonia, there's a set of general goodwill principles, an annual sacrificing of livestock in each city, village, and hamlet officiated by the local priest who also is occasionally called upon to divine various things, and a meeting of the priests for a series of livestock sacrifices every fifty years. Avalonians aren't specifically opposed to the Cassian faith, but to the idea of a large entity attempting to impose its foreign will on the people. The government, similarly, sees the Cassian faith not so much as a faith as a government siphoning the peoples loyalty. This coldness and lack of hospitality isn't the result of personal hate, but a matter of sovereignty and legitimacy for the existing system.
The Avalonians greet the Galaumians with due hospitality. The book is of moderate use in figuring out the language, and within little time the Galaumians can be understood by their caretakers and officials designated to address their needs. Information on their homeland is requested, specifically trading opportunities and openness to foreigners. Those aren't colonies; they're member states (okay, there is a colony up North).
