The Emperor discussed with Lin En whether he could remain on Terra, protected by the Adeptus Custodes, and draw cards over time.

He thought it over, then shook his head. "I don't think that would work."
The Emperor was surprised. [...Why?]
Lin En explained.
The plan sounded reasonable, but in reality, it probably would not work.
The system had mentioned from the very beginning that drawing Throne Liberation required something called Plot Points.

Judging by his past draws, if he truly wanted to
