To put it quite simply, Megalith is a large chunk of rock floating in space. The top half is missing, and so it resembles a jagged blade with a flat top (Note: Naga should make a visual aid). The smooth "top" (remember, there is no up or down in space) has several strange temples and monuments on it. It is an extremely ancient artifact, and seems to possess great power. The Drakonian Empire discovered (or re discovered) it 50+ years ago and began research and study. Megalith warps the fabric of space-time (overused terminology, ik) and can create or destroy universes. For example, it was used to create and maintain Aetheria, as well as collapsing the Ichiri universe at the end of the Drakonian-Ichiri war.
