The general eventfulness of their lives since they left Jakku seems to be at a bit of a lull. Which - good. Her apprentice has needed a break.
(Anakin's needed a break.)
She's taking advantage of this to introduce Lily to the joys of archaeology. Not at all sarcastically so - Anakin's second greatest pleasure since she's died has been helping Luke poke around ancient ruins, especially those predating the Old Republic. It's usually less dangerous than poking around ancient Sith ruins, too, and Anakin wants a chance to really hands-on introduce Lily to the history of the ancient pre-schism Je'daii Order. There haven't been any really major Force traditions emphasizing a balance between the light and dark sides since the schism, but the Je'daii took a different enough approach from the direction Lily and Anakin are stumbling toward to set interesting questions in front of the girl...
Luke was the one who alerted her that this planet, not really near any used hyperspace routes, might have an old outpost that he thinks belonged to the Rakatan Infinite Empire before the Je'daii managed to seize it in the aftermath of the Force Wars. It's pretty far from where he's holed up avoiding his sister, so she offered to check it out for him.
Which leads her and Lily to wandering carefully through a half-collapsed base, the main remaining structures the parts that were buried underground - the basements and bunkers, as far as Anakin can tell, though it hopefully included some storage. Anakin's floating ahead of Lily, paying attention for dangers - or anything delicate enough her flesh and blood apprentice shouldn't step on it - while Lily takes scans with a holorecorder and notes on a datapad. They'll go back through later to start sifting through millennia of accumulated sediment, after they have an idea of what they can access without digging.
She's glancing over her shoulder, teasing Lily - "Maybe we'll find some old weapon for you to impress that boy you've been teasing with - "
- When she steps into a less damaged room than the others, a sphere made of interlocking rings on a dark pedestal in the center, and it feels completely inert in the Force, no different from every other harmless speck of dirt -
The world spins around her, Lily's alarmed shout the last thing she hears.
