"Reills. E'en the name makes me shudder. That there is unholy ground, cursed by most gods. Not even the demons and devils and the incarnations o' evil dare step foot there. Reills. You know me, I think money likes it in my pocket instead of wherever else it is. But, and I've heard rumors that say this, if theirs treasure on that ground, it ain't going in my pocket on pain o' death."
-Old Gerald, man in the pub.
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.
