Which castle plots have the most NPC pathing though them and thus the best chance for servants to get into a scrap?

I'm willing to entertain that in my various PvE playthoughs I've somehow avoided this game behavior. Howweverm I built a castle on the western most of the 3 castle plots between Adam and Voltatia on the northern edge of Gloomrot North. It was mainly just for storage and quick access to crafting stations though did have a trio of torch bearing servants roaming around just for aesthetics. At some point I came back to the remnants of absolute carnage and evidence of what had to be one of the most glorious battles I would have ever seen in V Rising. This wasn't the remains of some poor trio of wolves that accidentally strayed into the castle's surroundings but what was at least 2 separate patrols consisting of NPCs that dropped bloods, hearts, cloth, mutant grease, tech scraps, etc and were enough in number to eventually overwhelm my 3 under-equipped torch wielding servants who's main job was just to create some immersion via moving light sources. Overwhelm them enough to send them back to the coffin.

I know Stunlock has a firm stance of "Not going to happen" when it comes to PvE raiding, however this incident added a new level of immersion to the game with just enough threat to make it worth combating but with no apparent long term consequences

Are there other castle plots where this is possible. Are there some where this can happen on a larger scale?
