It makes no sense to assume that they are different from the Daimons on Beluaterra.
Then... why hasn't there been an invasion? If your character knows how Daimons act on Beluaterra, then -- simply by virtue of Dwilight's long history of Daimons not acting like the Daimons on Beluaterra -- he ought to know that the Daimons on Dwilight are different.
Look, it's very simple: How many invasions has Dwilight had? How many invasions has Beluaterra had? Therefore, Daimons on Dwilight must be different. Your characters can know this even without ever having set foot in a Zuma land or swung a sword at a Moot-member.
Even if your character knows absolutely nothing about the Daimons on Dwilight, he can look at a map of Dwilight or open a history book and know that the Daimons have not managed to take over the continent nor have they done so in the entire known history of Dwilight, and therefore if your character also has knowledge of the invasions on Beluaterra (and has a shred of honesty and intelligence) he ought to be capable of admitting that so far the Daimons on Beluaterra have displayed a markedly different type of behavior from the Daimons on Dwilight -- EVEN WITHOUT EVER HAVING VISITED THEM. Your characters can still rightfully hold erroneous beliefs, be suspicious, prejuduced, ignorant, idiotic fanatics, generally poor at logic, what-have-you and so on and so forth. But this:
tMP believes what it believes based not on the Zuma, but on the BT invasions. What they believe is both rationally arrived at and cannot be proven wrong.
This is wrong. You cannot claim to have knowledge about the Daimons from Belutaterra while simultaneously claiming that the Daimons on Dwilight are exactly the same
and have come to this conclusion rationally.
