Iota Malephelos continued on its trajectory, flying clumsily now that the secondary guidance crews were all dead, and launched its full payload at the Keta Rho. The space around it sizzled with coruscation as the guns all fired at once, hurling a storm of ship-killing shells across the narrowing gap between them. Keta Rho attempted evasive action at the last moment, but it was too close to escape. In a series of sharp impacts, its facing flank was peppered with cannon bursts, shattering the void shields and penetrating down to the hull plates below.

Immediately, other Alpha Legion vessels started to home in on Iota Malephelos’s position, now alive to the switch of allegiance.

‘Come about for another pass,’ said Bjorn, watching the tactical display fill with enemy signals and wondering how long they’d last.

Godsmote made the adjustments just as the chronometer hit the two-hour mark. Almost instantly, the fallback order came over the fleet comm.

Lord Gunn had had enough – even he wouldn’t see the fleet ripped apart to salvage his pride. All across the battlesphere, assault rams, boarding boats and gunships would already be streaking back to their hangars, covered by whatever escorts had survived the initial melee.

The Keta Rho still lived, and was turning to bring its own weapons to bear. Six other enemy ships were hurrying up from the starboard nadir, all zeroing in on the Iota Malephelos.

‘What are your orders?’ asked Godsmote.

Bjorn didn’t need to look at the tactical displays to know what he needed to do. It made him sick to contemplate it, but there were no alternatives.

‘Broadcast the new ident,’ he snarled, tasting – again – the pain of retreat. ‘Then full-burn, back with the rest.’

Gunn remained at the helm of Ragnarok, glaring grimly out across the bridge of the enormous battleship. Below him, ranked across the dozens of terraces radiating out from the command dais, hund¬reds of mortals and servitors struggled to enact the withdrawal command without getting the ship destroyed. Alpha Legion vessels streaked in from every direction, now at full velocity, aiming to pierce the outer defensive shell and get in among the more damaged warships.

‘Maintain the perimeter,’ warned Gunn, flagging up a weakness in the sector held by Fenrysavar. ‘Get the gunships landed. Skítja, we need to pull those torpedoes out.’

The entire Wolves fleet was contracting, pulling in on itself and swivelling into retreat trajectories. It was a dangerous time, risking exposing the battleships’ flanks before they could power up to full speed again. Some captured vessels were responding to the command, but not enough to replace those lost in the fury of the counter-assault. The claustrophobic dimensions of the gas tunnel hindered them further, since straying into its margins would be as catastrophic as a full lance-battery strike, so everything was tight, constricted by the volume of incoming fire as well as the collapsing dimensions of the battlesphere.
