Tartus: Horizons of Ash: 4

When the war against the Masters expands beyond their own worlds, the people of Tartus face a terrifying truth: victory at home was only the beginning. Across the galaxy, thousands of portals are opening onto distant planets, each one marking another battlefield in a conflict that has raged for billions of Cycles. Entire civilizations are vanishing before they even understand the danger stalking them. To stand against an enemy determined to erase all life from existence, old boundaries must fall forever. Science, magic, faith, and the unaligned must now unite not only to defend Tartus, but to carry the fight into the unknown itself. Aboard the heavily modified Paracletus, Magnar and his companions prepare for the most dangerous mission ever attempted: crossing artificial gateways into unexplored star systems, seeking allies among alien worlds, and striking back against the Masters wherever they are found. But beyond the portals lie mysteries no one has imagined, civilizations unlike any they have encountered, and horrors waiting in the dark between worlds. And the farther they travel from home, the clearer one truth becomes. The war for existence has only just begun.
