Headscratchers / Furi

• So, why was the Voice imprisoned? Couldn't he just, y'know, leave?
  • Given that he was willing to go so far for his goal, apparently not. It's possible that none of the Guardians were ever supposed to leave and he'd have been stopped if he tried, or that one can't reach the planet from there while the Guardians still live.
  • Also, given what we know of him and learn of him later in the game, imprisoning the Voice could have been a symbolic "throw away the key" moment for the whole prison.
