Two cats that were board the Hindenburg, their owner named both of the sisters after those two zeppelins, They jumped off with some other friends under the zeppelin during the disaster, their owner didn't survive the disaster by getting smashed when the zeppelin fell. as the animals also got hit. apparently i decided to break the laws of science and they get saved by a miracle and then they get powers so they can break logic even further and travel time and alternate universes
