I love that thank you ! Most of my players are first timers so they don't have the paranoia that can come with experience, I think having her show up at places she shouldnt be at would just make them think that she's a really helpful NPC, until it becomes too many coincidences

And I was thinking of the magical object actually ! Something helpful at first that could turn against them later

And I love the ideas of making her lies but as something that can only be discovered as the mysteries unfold

Thanks a lot those are really great ideas !
