Strange symbols in TDD & AMFP

[Alardem]

The pigs in the altar and the stained glass make sense in the context of the story of AMFP, as symbols of sacrifice, even if they don't belong in a church.

The astrology symbols in the tombstone probably have no meaning whatsoever, I think the developers just reused that asset as a way of saying "see, here's another connection with TDD".

Exactly like how the pictures of naked people whipping each other is merely a reuse of Justine's assets, and couldn't possibly hint at Mandus being sexually perverse?

Can't be both, am I right?
