I agree with Lyssaria that you've made an excellent point, O Mower of Rocks, and it's one I hadn't brought to consciousness.

However, if they're making offerings, it indicates that there's continuity of or sympathy with the original culture. And when we learn the back story of the city builders, we find that this is significantly the case.

As for your analogy, at least some of my Wiccan friends would declare that they do imbue Stonehenge with equal significance, if not precisely the same, as those who erected it.

And since I'm Catholic, if I were on a dig that uncovered a 1st-century church I would declare that I imbued it with EXACTLY the same significance as its first users.

But Lyssaria is right, too, about LDW leaving room for different players to, if not make different interpretations, at least pay more or less attention to the non-Christian religion of our villagers.
