Though abundant on the northern continent of llsabard, only a handful of ceruleum deposits have ever been discovered on Aldenard, the largest being buried under the Sea of Spires in northern Thanahn. Ceruleum is a highly unstable substance and will begin to evaporate when in contact with air, resulting in the bluish haze from which this area earns its name. Camp Bluefug was built as a post whence armed men could patrol the Ceruleum Field Originally, this duty fell to the Brass Blades and Stone Torches. With the Empire's forces a mere stone's throw away, however, the Immortal Flames have since taken control.

Rough wooden structures with watchtowers, surrounded by a hazy, bluish atmosphere due to evaporating ceruleum.
