Kiadine was someone who split the chronon. He ripped time apart, reducing his people to "temporal slime". The Time Lords came and imprisoned him in a time locked dimension, and left to keep that reality in check. When Lloyd Collins was aged to death by one of the creatures on the world, Kiadine turned time back, bringing him back. The Master offered Kiadine to release his chronon powers in exchange for enacting revenge against the Time Lords. When the Master was defeated, no-one was left to keep time in check on the planet, and the planet tore itself apart. (COMIC: Doorway to Hell)
