You manage to notice, tucked away in a darker corner of the sanctum, a lone rift in reality. Nothing special adorns it or draws attention to it, but a feeling of forboding definitely fills your senses. Nikoro, noticing your interest, comes up silently beside you, holding his arm up in front of you. Slowly and calmly he speaks, "That portal is a strange one, it was here when I came about this place. I wouldn't dare enter it though, and I speak from personal experience. Many things reside there, the ends of all extremes. It can be rather unerving what you find in there as it seems to draw upon all things real and unreal, so if you must... at least go with my caution and assistance. Who knows how you might get back otherwise."
