As a man walks down the block he notices the address numbers change weirdly. He decides to investigate, and he goes to the department of mail and they give him a classified document. Apparently, the founders of the village deep in the 1280s created the system.
So the man went to the block the next day and saw his house was 624, the next house down was 1248, and the next was 2496. D
