I'm certain I could negotiate something with Sothis to help them too.

[But, as benevolent as Sothis could be, she could be capricious as well. Additionally, he was leery of relinquishing control to her, even if it could lead them back home, because selfishly, it terrified him. To feel something beneath his skin puppeting him from within, blind, deaf and mute to what was happening... even if it was Sothis, there was a visceral wrongness at being so thoroughly locked out of your own body.]

...but, I agree it would be something used more as a last resort. If it's even possible. [He didn't even know where to begin to try and boot Sothis awake.]
