K.J. Jupiter was born on the outskirts of Planet K-39.6, where he spent most of his early years frolicking along the space gardens and collecting star sparks. After earning his position as the leader of SpaceFleet-184, he spent many decades traveling the different dimensions and taking notes of the many wonders he saw. Now, parked right outside the Milky Way Galaxy, he has transferred them into books; the easiest way for his discoveries to traverse the galaxies. Don't worry, he's sure that your universe isn't in imminent danger of being destroyed.
...at least, he doesn't think so.
