After some discussion it is decided that Tathar and Smelkie will explore the immediate surroundings of the building, while Stockard will take a quick peek inside and the remaining two members will stand watch at the entrance.

Tathar and Smelkie

The three of you start walking around the building. The building appears to be as long as it is wide, all sides are made of the same material and appear equally covered in vegetation (mostly various vines creeping up on it). The surrounding area appears normal at first, until you reach the back side and Tathar spots some old tracks on the ground, following them you find the remains of an old campfire spot about 50 feet into the forest. Further investigation also reveals the tracks were made by medium-sized humanoids. Other then that, everything is clear and you return to the front side of the building again.

Stockard

Crouching low, Stockard slides himself underneath the portcullis, standing up again behind it. He is now standing in a short hallway, roughly 10 feet long, 5 feet wide and 10 feet high, behind which appears to be a massive room. Unfortunately the only light comes from outside and it only reaches into the hallway, what lies beyond remains in the dark.

[Amd and Tori

As both of you stand around keeping watch, nothing happens.
