The tunnel was made of several vines and branches that seemed to look like normal tree branches of the real world. The only real difference was that all the branches were tightly packed together making a safe walkway. Walking through the tunnel Vain felt like nothing around him felt even remotely safe. It was as if the walls would open up and reveal hundreds of entities.
Unfortunately, the pair could only focus on the mission, so with flashlights in hand the pair walked through the tunnels. The tunnel itself had several spots that seemed to randomly glow, but the spots weren't very bright as well as being so few and far between that only using flashlights could one see clearly.
