How can we be sure that Templar got ALL the members of the HoL?
In (or rather, before) 'Apocalypse Nigh', a semi-stable node to a system called Zeta Aquilae was discovered in Regulus around the time of Operation Templar. The node was not considered stable enough to enable safe exploration of the system beyond, but robot scout probes reported that it was free of artificial constructs except for some abandoned Sol-era mine workings (see Descent 2...) A monitoring station (known as Tirith Station) was set up near the node, but not before Operation Templar concluded. During the NTF insurgency, the station was abandoned, but once the Second Shivan War was over it was repaired and expanded.
In the last few years Tirith Station has again fallen into disrepair and abandoned. The node to Zeta Aquilae is unguarded.
Near the beginning of the story, we find out that some HoL ships traversed that node before Templar and now form the nucleus of a pirate force that has been raiding supply bases over the past few weeks. The Aquitaine is sent to Zeta Aquilae with two Aeolus Cruisers and a Deimos Corvette to mop up the pirate forces, and the Vasudan Emperor has deployed three Cruisers to guard the node in Regulus and recommission Tirith Station as a Vasudan installation.
However, it becomes apparent that there are more new systems beyond Zeta Aquilae. The Hammer of Light flees to the outer reaches of Zeta Aquilae, and jump to Quartzon. There, the Aquitaine discovers that the HoL has found another Knossos portal, and as a last resort to escape the wrath of the GTVA, they have activated it. The Aquitaine is ordered not to pursue the escaping vessels, but instead guard the portal.
