gollark: And why not just tell magic™ "these people are to be turned into pure memetic beeite in the most energy-efficient way possible"? Does it not like this?
gollark: You can happily drop heavy objects from quite high up, or fire bullets, with cereal bar amounts of energy, though.
gollark: In Eragon, you can do arbitrary things magically, but it costs as much energy as "doing it yourself" would.
gollark: But still, you would expect mages to carry around ridiculously energy dense carbohydrate slurry or something.
gollark: I suppose there is a limit to how fast you can digest cereal bars.
