Log entries[]

  • Personal log, Commander Michael Burnham. 
    My mother taught me the greatest mysteries come in threes. Birth, life, death. The past, the present, and future. That's where the Red Angel is from. We now have confirmation, thanks to Mr. Saru. The Angel is humanoid and wearing an exosuit made of future technology we've never seen. But whose future, and why? The only person who may be able to answer these questions is the one person nobody can find.
