Lucid dreamer

Many masters of the arcane have had dreams or divinations. Some arcanists have spent their time researching where dreams come from and what they are. Some have found that dreams seem to act like their own plane of existince. Some even have theories that our connection to the magic weave are through are dreams. Those that have studied this connection have learned to control their mind and enter a state of lucid dreaming.

The more time they spend in their dreamscape the stronger they become connected to the weave. When enough experience is aquired practitioners of this art can call upon their dreams and make them reality. To focus this connection arcanists will bring themselves to the brink of exhaustion.

Lucid dreaming is a draining process that drives many arcanists insane. Most are unable to realize which reality is true. Others bring themselves to the brink of death just to further blur that line in between.

Most dream cartographers focus on illusion, enchantment, conjuration, or divination schools of magic.

Arcanists who delve deep into the study of dreams and their arcane significance find that dreams are an untapped well of arcane knowledge and power. The best way researchers have found to extract that power and bring it into reality is to be in a constant state of permanent exhaustion, always being on the brink of permanent unconsciousness.
