The Ieahanea Telescope is a cutting-edge technological marvel built by the Ilyrion Space Agency on Valaralda. Its control center at Ilyrion University is described as a room "bristling with tech—holoscreens and haptic touch devices and other things he couldn’t name". The telescope itself "had just come online recently, and it was intended to peer into deep space, reaching outside the edges of the galaxy itself". It represents the pinnacle of modern Valaraldan engineering, a tool the elves are "quite proud of".
The telescope serves a pivotal narrative role as the instrument that first detects the apocalyptic threat known as the Fall. Scientists utilizing the telescope discover the "exotic space object" eventually named Guruthos hurtling through intergalactic space, traveling at speeds "significantly faster than light" on a collision course with their solar system.
