Teknall made a factory that produces Stellar Engine Collectors autonomously to form a Dyson swarm around his personal star.

I'll put a disclaimer here: the Stellar Engine itself is not a Holy Site. Rather, it is a piece of infrastructure which powers some of Teknall's things (with large quantities of otherwise mundane energy). One of those things happens to be Teknall's Workshop, which is a Holy Site, which contains said factory which makes the Stellar Engine bigger.
