A little meetup

A few minutes ago...

Somewhere within the depths of the inner sanctum the space rippled and creaked as a mass of tentacles carrying a golden shield on its back crawled out of a miniature wormhole. By the time the space had stabilized Mendax was already on his feet, dusting himself off while looking at the group of 4 individuals in front of him.

They were standing on a small island at the edge of a waterfall. The water was pitch black and it flowed in reverse, going up the waterfall instead of down but, that wasn't even the strangest thing about this place.

The entire space, both up and down, was divided into two completely different halves starting from the edge of the waterfall.
