The Tree had done their homework and the Chroniclers this time coordinated their attacks against Solus instead of fighting as individuals. They covered each other's back, exploiting the openings that Solus' attacks created and forcing her to turtle up.
Until that moment, she had failed to kill anyone after Uldreyin.
'It's done!' Vamir alerted Solus the moment the Engine was fully formed and the link with the mana geyser established beyond what the World Tree could cut off once they stepped off the exposed ground.
'Fire in the hole!' She replied while pointing at the still-open blast mark left by Thundercrash.
The Librarian nodded and fired the electromagnetic cannon. The shockwave alone sent the Chroniclers slamming against the wall while the noise burst their eardrums. It wasn't enough to kill them, but that was Solus' job.
