Speaking of biology, the status of mortal minds is quite obscure right now. Very little attention or might was sort in the brain, less than the last one, apparently.

Of course, mortals still kinda do have a good mortal mind. But it is unclear how much like ours it is. Dreaming for example, is an entirely different beast than how it truly is.

For example, if someone somehow managed to cut off the mortal connection with Raka, what would the feasible results be? Yes. It happened once in the distant past, but that was before modern mortality and actual complex dreams.
