Woe is an extremely hazardous planet in the Josian Reach Sub-sector of the Calixis Sector which has been designated a Death World by the Imperium's Administratum due to its dangerous species and environment. Little is known of this planet, other than its reputation as the home of a collection of the most vile creatures fathomable.
It is regarded as a place where the Emperor of Mankind's light does not reach. Woe was visited by Inquisitor Felroth Gelt and his retinue of Acolytes in 770.M41 whilst pursuing survivors of the Brotherhood of the Horned Darkness Chaos Cult controlled by the daemon Baphomael.
After this encounter, during which the world itself seemed to be consciously alive and hostile to the Imperial intruders, the planet was determined to be a Death World and was declared off-limits to Imperial settlement or exploitation by the Inquisition.
