Ghostly Spires

Our … have set their camps around the edges of a glassy, frozen lake. Under sufficient light, one may catch glimpses of spectral towers underneath. They grasp upwards from the lake bed like steadfast tendrils. Our less experienced crews are still adjusting to work in such biting, sterile cold. Despite this, our excavations have proceeded swiftly. We have exposed numerous airlocks, all designed for primitive submarine vessels. There is, as yet, no sign of the vessels themselves. Whether the tower's inhabitants stayed or fled, every one of its docks was left empty.
