User blog:Zombspider/Strange findings in the Woodland Realm?

Recently, whilst messing with some stuff in Mirkwood, I came upon this odd structure. In the middle, there was a large tree and its trunk was made from gravel and its leaves were solid gold ore. Have the Wood Elves been attempting their own golden wood? Next to the tree there where two sphere-like objects made out of hardened clay with wool carpets scattered among them. The spheres floated and below them stood numerous Mirk-Oak wood stairs and some Rohirric brick. I'm playing on a single player world which I generated yesterday and can be certain nobody else has built this. On top of this, a nearby Wood Elven tower has been split half way through making me believe that this was most likely a hidden structure. I'll withhold the coordinates for now as it may be, I hope at least, an easter egg and I'd hate to ruin the surprise. If this isn't a previously undiscovered structure then what is it? I really hope I'm not being idiotic and forgetting something right now...
