Tatters, the answer to your question is how much weight you want to be able to put behind that strength. You can say "my character is strong" and do strong character things, but if that's just part of the description, you don't have much backing if I tell you later that an NPC is stronger than Constance, or that she's not positioned to overcome a problem with strength. If you list a trait, it's more fixed, you get to mark it over damage and tell us how it protected you without narrative interference from anyone else. So if you want the last word on being able to say "I lift that boulder and heave it away" without anybody being able to contradict it, that's what the mechanical trait is for.

Also, answer the questions I asked you, Tatters. =P

Stveje, these are great, love the hidden castle. I kind of just want you to name the goat goddess Romme or Rom (as in the middle English for Ram). That description of their land and practices is very clearly Scotland, so they'll be from past the Northernmost part of the kingdom, and the castle will be a place of power there. I expect things are a bit more wild and chaotic in their homeland, but also less corrupted and dying than near Camelot.
