Pills were a curious bunch of things when it came to rules.
The rules were very weird, making little to no sense when it came to how they had to be. Some of the weird rules included the fact that pills needed to be symmetrical.
Other weird rules included that if two pills had the same amount of energy, but one energy was more condensed than the other, and it would have less Harmony. Thus making the pill with the condensed energy appear as the worse pill. When in reality, they both had the exact same amount of energy, with the only difference being a bit of powder remaining stuck in one's body.
Another weird rule was that pills didn't have an exact requirement for what was considered a pill or not in terms of size. There was a general range of size between which any pill could be considered the same as any other pill, even though it was clear that a smaller pill with no empty space was no doubt going to have less energy than a larger pill with no empty space.
