After solving the mystery of the stolen treasure, Edison is all set to return to his alchemy, when his friend Omar shows up at his door pleading for help. There is something or someone living beneath the blocks of Omar's town, and things have started to take a treacherous turn. What started out as the theft of livestock and wheat has escalated, and now villagers have started to go missing as well. Edison tries to convince Omar that he's not a good fit for the job--as he only solved a local robbery--and sends his friend on his way. But a few days later, Amira arrives with bad news--Omar is the latest villager to disappear. Consumed by guilt, Edison recruits Billy and they set off to rescue Omar and face the mysterious villain lurking beneath the blocks.
