I don't know of any lore here. As far as I know Tiamat would be a different pantheon from what the oriental dragons care about, so I imagine they will not care much about them... if they are knowleadgeable enough to know they are a thing. If it comes to bother them they will fight it, but besides that I don't think they would get involved or care about the results in one way or another.

They will follow whatever the guys up top say they should do.
