2 How?

How did this happen? In a random planet a wizard fucked up his breakfast making spell and accidentally transformed everything in the universe into bread. The fuckup of his spell was so bad that the entire planet was instantly transformed into a loaf of bread.

This was no ordinary large loaf of bread though, it was a magic bread. This magic bread mutated and gained strong absorbing properties.

Before anyone in the planet could react, they fell into bread pores that opened up everywhere and got absorbed by the magic bread planet. Even those that were flying at the time found themselves sucked into the pores that the magic bread created. There was no escape, all lifeforms that was on this bread instantly became nutrition for this magic bread to absorb.

Once absorbing all lifeforms, the magic bread exploded into trillions of smaller magic bread that landed on nearby planets. Like a parasite, the breads dug into the planets it landed into and slowly transformed it into another large loaf of bread. Soon it would explode again, repeating the proccess.

And that is the lore of the bread universe.
