Heinrich Wilhelm Matthias Olbers’ Telescope

Origin
Heinrich Olbers was an astronomer, observing comets and asteroids, proposing the asteroid belt between Mars and Jupiter were the remnants of a destroyed planet. He also thought of Olbers’ paradox, which went under the assumptions of the universe being static and infinite. If every line of sight ended with a star, then the sky should always be lit, contradicting the absence of light during nighttime.

Effects
When peered through, it glows and transmits an extremely bright light. It’s effect has proven benign, as it is strong enough to light dark, cavernous spaces. However, it will never operate when in the daytime or in a well lit location.
