If you guys want to go deeper down the rabbit hole here, I’m piecing together solicit clues.
So, in the Charles Soule book, Light of the Jedi, the Eye of the Nihil, Marchion Ro, has access to special hyperspace lanes that are not known to the core worlds, the republic, or generally to anybody except the Nihil. These are untested, wild “Paths” through hyperspace. It’s what give the Nihil the ability to seemingly appear out of nowhere.
Looking at the new Star Wars solicits today, I came across the Doctor Aphra #9 solicit (April 21, 2021):
LOST TECH! CRIME SYNDICATES! ASSASSINS! DOCTOR APHRA and SANA STARROS’ search for the NIHIL HYPERDRIVE gets deadlier as GENERAL VUKORAH and THE UNBROKEN CLAN enter the race for possession! What powerful secrets of the HIGH REPUBLIC era could the lost technology hide?
So, it would appear that the mission Aphra has been on, as tasked by the Tagge family since issue #7, is to recover the Nihil hyperdrive, potentially giving the Tagge family access to the Paths of unknown hyperspace lanes.
In issue #6, it’s referred to as a “Path Engine” of “Nihil Design.”
In issue #7, the artifact is simply referred to as “The Engine”.
So, we’ve already seen the thing in a hologram twice and we know it’s name and its origin. However, I’m wondering if we’ll get flashback sequences to the High Republic times, maybe some holograms of Nihil characters. There’s even a woman that Marchion Ro has kept in stasis for hundreds of years in the book that could potentially resurface as an ancient “Path-Finder.” I’d keep my eyes peeled on these issues as Alyssa Wong brings the Nihil and High Republic concept into the original trilogy era.
Caveat: I haven’t finished Light of Jedi yet, so I don’t know if the woman in stasis dies before the end of it.
