Lodart is a dark-blue mushroom that has a finger-tall stalk and cabbage-sized cap. It contains powder-like spores inside that, when inhaled, gives the users "wake dreams," or hallucinations similar to dreams that could be either nightmares or not. Aside from its mental effects, its physical effects are: weakness or drowsiness, numbness, and heightened sense of smell and taste.

It is often used as anesthetics by doctors for those who suffered serious injuries for them to be able to heal the patients with ease. Also, chefs use it to assess their meals that they served for high-ranked nobles, until it was illegalized because of its addictive effects.

The word "Fog," often used as a term to describe someone's stupidity or madness, is derived from the natural phenomena in the sea called "Sea Fog."

Sea Fog is a blue mist that appears after a stormy night, which often gave sailors hallucinations of hearing monsters, and often harmed each other because of this. Although this sounds like a serious case, the effects could be removed by physically stimulating a patient with a strong slap in the face.

Not everyone could be affected by the effects of Sea Fog, though. Those who are weak-willed tend to fall prey to this, and were looked down upon, hence giving birth to the semi-insult term.

Oftentimes, the word is used as "Foghead," a term that commoners and peasants love to use. It sounds vulgar and informal for the nobilities.
