Hellabore

Hellabore is an Imperial world for which no segmentum, sector, system, or coordinates are recorded.

In 867.M41 Craftworld Iyanden killed its planetary council, which Iyanden’s Farseers had foreseen would fall into damnation. The Imperium, unaware of that purpose, sent the Crimson Fists Fourth Company under Captain Alessio Cortez against the Eldar. Most of Iyanden’s host had already withdrawn by the time the Astartes arrived.
