Also, a random thought I had, but it's interesting that Copper's goons weren't seemingly expecting heavy Name support. Like, sure, it makes sense if Copper hadn't seen either Marinette or Biedde in the Mansus, but… did she not even scry for Velvet's possible defenses? It's not like we have Wards set up to defend the mansion or anything…
I think Copper is in a weird situation in which she
thinks she's knowledgeable about the Mansus, but really isn't. If you think about it, Grail is her primary Lore, and she likely has a decent chunk of Winter given she has Neighna. However, with how the original cult was set up, she wasn't in charge of developing the cult's knowledge. She was in charge of recruiting. And the actual amount of "stuff" we provided was the cult wasn't... much.
Primarily, she's aware of Windigos, as we saw in the attack against us. She only used a single one if her attack, but unless I'm remembering incorrectly, not that many were brought to the Changeling Hive, and the Changeling Hive was
destroyed. I personally believe that she did scout us, as the map was already mentioned, but if her scouting took place last turn, she would have seen Comet guarding us and... that's it.
To take on the 2-health Velvet and Comet alone, 4 edge-aligned ponies and a Windigo
should have been enough. Mareinette was around, but she never really left the basement we stuck her in. And Biedde didn't appear until
this turn.
In fact, our decisions look like madness to her. Here we are, an opposing cultist, with two
Names working under us. Why would we ever use such powerful entities to do something as mundane as guarding our home? Why would we not be using them for "better" actions more in line with the Lores we're aware of?
So, she sent the attack, and it failed. With the information she has, Copper has to despise us even more, too. Her scouting last turn would have reported a poorly guarded manor, but yet, out of nowhere, two Names she's never heard of suddenly appeared and Velvet was empowered with Edge? While I doubt she has a way to learn of this given everyone involved is now dead, it almost feels like we set this up just to trap her. I can't imagine what she might be thinking right now.
