Huh. (Do we need spoiler tags when the thread's explicitly about the end game?)

Honestly, I still don't see it as a connection with Azem themselves. Azem never would've needed a device to travel between reflections, because they didn't exist. (And we know Azem was sundered, because the WoL is a reincarnation of their shard on the Source, so they couldn't have just made it later or something.) A mystery to (hopefully) be explored later, I suppose.
