Bakka

Bakka is the naval base of Segmentum Tempestus, a young mineral world whose surface is lava seas and black rock rafts. Shipyards sit on those rafts behind adamantium walls; the air will kill you without a mask. Battlefleet Bakka has bled for Macragge, Fenris and its own moorings. Irregulars from this world fight as mass infantry off the fleet decks.
