The brimming displays that fill the Royal Museum of Natural History in Evenhold are unrivaled in central Addar and represent one of the most comprehensive collections of natural and cultural artifacts in all of Eamon. The museum contains specimens of plants and animals collected from all around the world, along with mineral samples, fossils, and historical artifacts from innumerable civilizations.

Queen Oziphor, a keen naturalist, founded the museum in 480, transferring tens of thousands of curiosities from the royal archives into the museum's collections. The queen ordered an Anharic-era mansion along the Avenue of Swords converted to house the museum, and commissioned the construction of an adjacent library. The museum has since added several new wings to properly display its expansive holdings.
