Yraii City
Alec gathered all his Spectre subordinates with the exception of Dominque and briefed them before informing Dorian of anything.
After doing that, he cleared it with Dorian, saying that they were going out on a mission.
Dorian had raised a brow and given his stamp of approval quickly enough after hearing the rundown. What kind of mission would require the entire unit of Spectres, who had been rapidly growing in the sect, instead of having a few teams?
The sect leader knew that it wasn't as simple as Alec told him, likely a lot more complicated judging from the paperwork, but he approved it anyway.
The Spectres listened to Alec before anyone else for numerous reasons, but Alec listened to him.
The reason he approved was because he knew that Alec wouldn't place his Spectres in harm's way if he could help it. Which meant that there were necessary precautions in place. Minimal risk.
