I had a long rant written for this, but I deleted it because I realized getting angry about things isn't going to help me get answers.
Basically, I'll admit I'm agitated by how vague the information on Daimons and Aspects is in RoP:M and TMRE. The TMRE examples of Daimons are only somewhat helpful in figuring out how strong Daimons are and how much influence they can have because it doesn't very clearly describe the relative strength of Aspects to their Daimons. (At the very least, though, it's fairly easy to assume that the given Daimons are actually Daimons, since the main thing one does with Daimons per TMRE is summon them, which requires knowing their Might.) RoP:M clears this up by saying the Aspect can be as strong or weak as the Daimon desires and it's free for the Daimon in any case. But it also compounds the issue; for a book that normally did a really great job giving me a relative vantage point of how powerful various magical beings in Mythic Europe are, particularly compared to each other, I have no idea how strong the given types of Daimons are, because the section leads off with the almost infuriatingly vague statement, "All the game statistics for spirits in this section represent Aspects rather than the Daimon itself, which usually has a much higher Might." (RoP:M 107) In other words, it's up in the air entirely, and I have no direction for how strong Daimons are actually supposed to be compared to various other things. I mean, most of what I know about medieval European beliefs comes from these books, and everything I know about the setting of Mythic Europe comes from them, so I don't really know how things are all supposed to match up. I could just wave it off with a "deal with it when it's relevant" thing, but it's relevant fairly regularly; if anybody tries to summon a Daimon's Aspect, that plays against the Might of the big guy himself, according to TMRE.
So... Yeah. The long and short of it is I have no idea what appropriate Mights are for Daimons of the various types. I know it could be called a YSMV issue, but variations have to be made from some kind of starting point, so not having one makes my job quite hard. Can anybody give me some more solid guidelines, or at least a better idea of how to figure that stuff out for myself?
