I made a perception roll and got a 10, I don't what modifiers there are but Gaea would mostly be using her seismic sense to know where she was, which is a targeting and ranged touch sense that has 360 degrees but only perceives those touching the ground. It doesn't go through barriers, yet, but just as one can hear someone around a corner I think she could perceive people around corners and behind small barriers as well.<br/><br/>In case Gaea notices what is going on with Stardust I also rolled ego because of her nymphomaniac complication and rolled a 7, which unfortunately ;D ,  seems enough.<br/><br/>Let me know if she missed or not and if I should roll something else. :)
