Arctic Vault (Chapter)

"When the humans discovered the giant artifact they later named 'The ETAC', they quickly realized it had to come from a society with far superior technology than anything indigenous to Trunkopia. To keep the discovery safe, they built a formidable defense around around it. If there are any robots left defending the ETAC, this will be their last stronghold. Hopefully, this is where the last cipher is located." - Chapter Description
