Interesting. It does bring up questions.

Why would Gortash think it a good idea to send a single nautiloid piloted by a mindflayer to the heart of the empire of the mindflayer's arch enemies?

Was Gortash's heist successful? Or was Shadowheart succesful?

What did the Emperor do when the nautiloid crashed? He hid himself in the prism which was in Shadowheart's back pocket, who fell to unconiousness but could have been killed? And at the same time, while he was inside the prism, did he negate gravity on Tav? How does that make sense?

And did the Emperor tadpole us before or after he was freed from megabrain's control? His unlikability depends on it.
