Tales of the Troll Markets first appear as early as 12,000 B.C.E., in the region now known as the Sahara Desert - then, a lush and fertile paradise. As the climate grew arid, the human and magical populations migrated outward, spreading across Europe and Asia. In 1836, occultist and explorer John Deak discovered a thriving Troll Market underneath the London Bridge. Deak's diary, containing detailed notes and drawings, remains the most comprehensive human record of the Troll Market of that time.
