Artificial intelligences---pursuing their own research and goals---but Soul/Sage/Lore can command them---since his own ability includes interfacing with electrical/cybernetic systems---especially Zha'Tahn cybernetic systems.  With others, they retain their own volition. Save with Soul, they aren't servants---but they are a valuable resources, valuable allies.

I like them setting up shop below where humanity has spread, also...the Deep Realm.

You'll notice that Beastbeauty, at least, has no desire to deal directly with them---again.  Once, in her case, was more than enough. That'll be explained  in a few weeks. 

Next time, we'll learn a little about Soul's first contact with the artificial intelligences who will later migrate to the Deep Realms.
