Unending Alloy
The statue was tall but quite narrow. It depicted the Unending One in an upright posture with its maw opening up as if to swallow the heavens. Its numerous tentacles stretched out from across his length and curled up in random directions in a chaotic pattern.
The only exception was the base of the statue. Due to the awkward nature of making a statue of a whale-like creature in a vertical posture, the bottom needed some support.
The solution chosen by its original crafters was to cleverly curl some of the tentacles of the dark god into a somewhat flat base. Enough tentacles pooled downwards to provide sufficient support for the statue in any environment subjected to gravity.
Of course, a more elegant way to keep the dark metal statue upright was to cancel gravity entirely in its presence. In fact, the aliens could have integrated such tech in the statue itself.
