This is the stronghold and birthplace of the daelkyr Belashyrra. The Lord of Eyes imagined the beholders and brought that vision to life, and the Citadel is home to a host of beholderkin. Tiny floating eyes buzz about like insects. Millipede-like creatures have rows of eyes running down their backs. The true beholders are mostly focused in deep contemplation of specific things, and don’t pay attention to outsiders unless they’re disturbed. Some study strange paintings. Others watch scrying pools reflecting images of Eberron or other planes. And some examine seemingly mundane objects, such as a rusty iron key, a dead rabbit, or an expensive hat. However, there are a few that patrol the Citadel, watchful for intruders.

The surfaces of the Citadel are made from an iridescent material that your eyes can’t quite focus on, as if the walls and floor are blurred. There are mirrors spread around the halls. Some run slow and show you younger than they are; others show glimpses of the future. Scrying pools reveal secrets you don’t want to know—current events on Eberron, scenes from the past, or the possible future.
