The hunt has begun. On the gue’la world of Halfus, Shas’vre Fal’shia Bas’reh Valel pilots his Riptide battlesuit against the might of an Adeptus Mechanicus armoured division. With over fifty battle tanks of the Imperium seeking his destruction, the odds are not in Vre’Valel’s favour. But the Riptide is the pinnacle of tau technology and Vre’Valel is a master of the kauyon – the doctrine of the Patient Hunter. Victory will be his, for the Greater Good.
