Please don’t see my messages like annoyance, i will just throw “memory bricks” that come to my mind just in case they help a bit. You don’t even need to reply if you already checked these areas.
North.
Under the layshrine we do surge, from the east side it has a big empty cave.
To the wolf vault entrance, cave small.
South.
It has a cave with gas close to the camp we take Brutus, southern.

Once @sestus2009 send me a photo with a rabbit shrine, i don’t remember exactly where it is and tbh, i cannot recall if i ever find it too.

Thank you for running around to help us.
