Son of Thor concept for an upcoming campaign

[Tsunami]

And we don't have any evidence that Holy Water made by someone without True Faith powers works at all. Harry's is all supplied by Father Forthill...who is a True Believer. In fact, due to Harry's discussion of why Holy water works (infused with a charge of positive energy)  that actually makes good metaphysical sense, too.

And being a True Believer is easily as rare as True Magic.

Actually, we do not have any hint that making Holy Water has anything to do with Faith powers...
True believers are the pinnacle of the power that Pure Faith can generate, and i'd allow any True Believer to make Holy water, but it's not a prerequisite.
It is Faith and Holy stuff and all, but basically every Priest can make it, it doesn't even matter which religion he or she follows.

So even if True Believers were as rare as true Magic users, which i don't think they are, Holy water/Stuff would be much more common.

Personally i'd have built the Denarians with a 3 point catch. +2 for availability +1 for researchable (and that would be more to find out what they are than finding the catch... once you know they are fallen angels the leap to holy stuff as a catch is quite easy).
But thats just me.

So, now i'll stop dragging this into a discussion about catches. That's not what the OP wanted.

@OP
Northern religion is something that has been on the descent for a long time. You could consider something along the lines of "Child of Times long past" as an aspect. Maybe he grew up in a mythical village without all that technical stuff, the huge crowds of people, and the generally high pace of modern life. Now he's supposed to learn the ways of the modern world... That would make him awkward in  our society and make the thees and thous you wanted quite fitting.

Obviously that would be an aspect prone to change during his development. Maybe into something like "Keeper of the old ways" to denote that he now has come to grips with the modern world, but still clings to the Old Ways of Honour, Hospitality and the like.

But that's planning a bit far ahead I think.

And your basis for this statement is? The only Holy Water or other Holy Stuff we've ever seen, even among Wardens who fight the Red Court alot, is what Harry gets from Forthill. If it were that common, it'd be part of their standard gear, wouldn't it? I'll admit it's never stated outright but the evidence is compelling.

Personally i'd have built the Denarians with a 3 point catch. +2 for availability +1 for researchable (and that would be more to find out what they are than finding the catch... once you know they are fallen angels the leap to holy stuff as a catch is quite easy).

If it were as common as you're suggesting, so would I. Which, since I tend to assume the folks at Evil Hat know what they're doing, would tend to indicate that it's not that common. Hence my current opinion.

True enough. 

In terms of Trouble, Tsunami's idea would definitely work, and do so well. Other possibilities are:

Honorable To A Fault - Thor's mostly an honorable sort, and a son of his might take this a bit further, becoming honor bound to do anything he says he will, and otherwise have it be a problem for him.

Protector Of The Weak - Again, Thor's a nice guy. Perhaps his son feels it necessary to walk in and save people being beaten up by bullies, assault Red Court strongholds to save their people, and otherwise behave in a generally helpful and protective fashion. Easily compelled to get him involved in just about any plot, and readily combined with the honorable idea above.


Something regarding a bad temper and/or arrogance is generally appropriate for demigods, but Thor's a nice enough guy to make that seem wrong to me.

Obviously the high concept is "Son of Thor".  Right now I am mostly thinking about two issues.  First, what's his trouble?  I've thought of Like his Father before him (e.g. wants to be like dad), One of the Asgard (e.g. their enemies are his enemies and other such things), and "I am the Son of Thor!" (really dislikes concealing his identity).  Anyone have other ideas?

Why not combine all of those ideas and problems into something like "I Am My Father's Son". That gives him his being like dad whether he wants to or not, makes all of his Father's the Aesir's enemies his own, and also plays to him demanding his birthright from non believers and keeps him form concealing it from his and his father's enemies or others looking to use his family connections for their own purposes.
