The Heart of the Pharos (Audio Drama)

The Heart of the Pharos is the thirty-sixth audio drama for the The Horus Heresy series that was not originally released as part of an anthology or other release. The Heart of the Pharos was first released as an audio drama in February 2016.

Official Synopsis
The Pharos stands as a beacon of light in the darkness, a whisper of hope in the silent void, a bastion of defiance in the face of treachery. Without it there could be no Imperium Secundus – why, then, do the masters of Ultramar know so little about its operation, or the dangers it could present? Young Oberdeii and Tebecai, Scouts of the 199th Company, descend into the depths beneath Mount Pharos in search of the truth... though it may haunt them for all time.
