Oh, of course, that's the primary conflict of the game. There's the main church that's based primarily off of Catholicism (at least, when it comes to architecture and iconography) that has knightly orders going around and crusading, looking for the Holy Grail.
Meanwhile, there's the Underchurch. Way back, there was effectively a Unification instead of a Schism in the church, and these guys refused to integrate as one. They're based primarily around Orthodoxy, and they're also crusading, it's just that they're treated like a dangerous cult, and most people have forgotten about them. Their knights became helmed horrors/shield guardians/giant constructs, their worshipers became skeletons and different flavors of zombies, and the highest members of the church are either ageless or have went full Lich. They're looking for the Holy Grail too, with the undead endlessly digging around underground, sometimes rising up and emerging up at holy sites looking for it.
That's legitimately a good idea though. Maybe a temple that contains Caliburn (if we're going for knightly, arthurian-inspired shit), the favored weapon of a long dead, great, king is being sieged by the dead/automatons?
What's interesting is that:
A) If the players are moving through the Underchurch, they can march behind the dead, and eventually perform the mother of all sneak attacks and maybe take out some sort of mummybishop from behind the ranks, crippling the undead that are dependent on orders from a higher power.
B) The undead could enter through some super secret, long forgotten, burial chamber or tomb that only the heads of the Underchurch are aware of (due to everyone else who would know being dead). This could contain clues to get them closer to the Holy Grail.
Well played, user.
Agreed.
The issue is that th
