Trench War

More findings from the excavation sites on … have come in, and with them a new theory for the origins of the trench network. Millennia ago the planet was beset by an invading extraterrestrial organism, best described as a huge snail-like creature the size of a city. It roamed with impunity, scouring the surface clean of all organic matter it touched. The trenches were dug out by the indigenous population of diminutive mustelid-like humanoids, in order to either escape the snail's onslaught, or to try to attack its vulnerable underbelly. By the extent of the excavation, this trench war must have gone on for generations, perhaps centuries. There are no indications the local population survived the crisis, nor are there any remains of the behemoth that devoured them. A grim fate, indeed.
