It seems like Guardians are essentially immortal as long as they have their ghost. You can jump off the tower as many times as you want and your ghost will resurrect you every time. This sort of makes Guardians an intimidating force to face when you consider that they are more or less unkillable. The only way to really put down a guardian is to take their ghost, denying them their resurrection (unless you're a filthy Sunsinger!). But if you died and dinklebot finally stayed inside the trash can, could someone else's ghost revive you too, or are they only able to revive "their" guardian? We found that dead guardian on the moon, and dinklebot didn't seem consider doing anything about it. Or was it maybe impossible to revive them because "there (was) nothing left, not even the light".
