Infractus is a small planet close to the far Rimward edge of the Thule Sub-Sector. A former research colony, the equatorial band of the planet is now a single Warp rift that circumnavigates the orb. Vox transmissions coming from the rift have drawn the attention of The Inquisition, as the dating codes on them seem to be from during the Great Expansion and the time of the Heresy. Attempts to research the emissions have proven to be fruitless thus far as the surface of the landmasses seems to be in constant flux near the rift. Inquisitor Rolf Sortjarl maintains his orbiting listening post trying to decipher the meaning of the messages, but refuses to send anyone to the surface. Despite this, multiple individuals have claimed, even under excruciations or psychic probes, to have come from this world. How they escaped, or who (or what) aided them, is still unknown.
