History of Agent Yero

Agent Yero is a Department of External Observation agent who went missing during the testing of Project BLUE DOOR, an interdimensional tunneling device meant to allow faster-than-light communication without breaking causality. Early tests failed and the project was shelved, but Director Moffat revived it because he believed the tests had pulled Dr. Davis and Agent Yero into another dimension. The 1967 Introduction Letter from lead researcher Dr. Annalise Meyers describes the project's early results.
