Sonic was the first real sky of the Midnight Moths. The original collection lived there as ERC-1155 tokens—an important detail, because the chain remembers ownership differently than a standard one-of-one ERC-721 collection.
That technical shape became part of the lore. A moth could not simply be looked up with ownerOf and declared accounted for. Balances mattered. Bridge custody mattered. The difference between what a wallet displayed and what the contracts proved mattered.
Sonic below was not a disposable origin chain. It was the forge. Any new world worthy of the moths had to preserve that history rather than overwrite it.
