Hera M.E.C.A

one day, on a walk through the forest on a certain path, on the distance you spotted something weird, a huge mark on the floor, only it was not visible to the naked eye since it was still covered by grass, you got closer and... yes, a huge foot mak, but it is deep on the floor, then you spot a path of broken sticks and leaves over the floor

you follow the path for around 15 minutes when you spot something pretty peculiar, a pile of grass and dirt and... metal? you tap the grass, it's too hard to be dirt, you knock and what seems to be a mechanical eye opens right from the grass, it locks on you
