The Avalon Expedition stands its ground.

Faced with the reality of remaining stranded in a mysterious nebula 3,000 light years from home, the Avalon Expedition has no alternative but to reclaim their captive Gatehauler from the depths of the Advari Empire. Captain Cassandra Farren and the rest of the Expedition's multinational forces at last go on the offensive, launching a daring mission to infiltrate the enigmatic minefield known as the Aegis of Invia, where much will depend on former Inquisitor Castian Vadric. But Vadric faces a far greater struggle from within.

The conclusion to the first season of the critically acclaimed audio drama 'The Sojourn', Volume Four takes the Avalon Expedition into their darkest hour, as loyalties are strained and courage tested in the face of nigh-unstoppable odds.

Directed and produced with careful scientific consultation, The Sojourn captures every detail of life aboard ship, from the sounds of the smallest airlock seal to the largest space battle. Featuring a full cast of veteran voice actors, backed up by high-quality sound effects and an epic original soundtrack, The Sojourn is a unique and striking audio experience.
