The journey had been a long one and now they had entered the mountains. After an entire day spent on paths cut into the mountainside and through moss covered coniferous woods, they encounter a desperate young mountain tribal. He is searching for his beloved wife and his elder brother, both of whom he got separated from after an unsuccessful attempt to kill a cave bear. The last thing he saw was the cave bear in full pursuit of his wife. He could not help her as he had been knocked to the ground by the raging beast, and was struggling to regain full consciousness. The tribal will be clearly nervous and urges them to look for his wife during their travels. He will stay in his village a couple of miles to the north and pleads for assistance should they recover his wife, whether she be dead or alive.
On the next day of travel, they will journey upon a dim track in the forest and while they are preparing to ascend another path cut into the mountainside, they hear moans of lust from somewhere nearby. Upon closer inspection they will spy a young tribal woman in the heat of the act with an elder tribal male. They are consummating their forbidden love on the cold mountain moss, and beside them lay the skinned and slaughtered carcass of a huge bear.
Coinlake sits perched between two sheer cliffs in the Stigrani range, and is difficult to find, much less approach. Four miles long and two across, the water is a vibrant cyan blue. The lake's shoreline is an unassuming beach of gray pebbles, and its mean depth is seventy feet. The rare times when the sun makes its way between the cliffs and shines over the the still water, one could see clearly the lake's rock-strewn bottom.
Strangely, no fish or aquatic life can be found here.
At night, a peculiar phenomena occurs. When the night sky is clear, the moon and stars are reflected in the lake's surface, but if one were to look at the surface from a high vantage point, the reflection does not match the firmament above!
Instead the water's surface reflects the night sky of some other distant world and seventeen shining golden moons besides, each ones shimmering upon the water like so many gold coins!
Legends whisper that Coinlake is not a lake at all, but a gate or nexus, to some distant alien world.
The mystery has long remained unsolved, and only recently has the Arch-Duke commissioned an expedition to uncover the secret of Coinlake once and for all. Among the team members are several scholars of the Nascent Academy, an astrologer from the Occultists Guild, and of course the PCs, acting as body guards.
