3H Common Route: Yeah, some NPC does say that but I assumed that like... Rhea knows the whole layout since she's been around forever. ...She's just uh... not entirely sane so... maybe she overlooked it and/or put too much trust in the Knights to suspect a problem that close to home even though another NPC mentions there was some resistance to Jeritza getting his position the way he did. Also they must have patched in some new NPCs because there's 2 new ones in like Chapters 4-10 that tease its existence that weren't there at launch. Which actually suggests it is known! One of them is right outside Rhea's audience room cursing the "Abyssians!"
