From what we see in your mind, you have tasks which concern you. And it seems your current form is more hindrance than help. We can address that.
Suddenly, you’re standing in front of a very confused grebling child, who looks up at you with a terrified expression while holding a spine.
You’re not sure that’s what you actually wanted… and for that matter, how did they get you a body? Yours is, or was, in a space between dimensions, and if they moved it somehow that could interfere with your return.
Well, as you get a clearer grasp on your surroundings, you realize that the body you’re in isn’t your own. It’s the corpse you saw earlier, the “Keeper of the Mysteries”. That still doesn’t clarify how the fungus brought it here or put you in it, but your more immediate concern is how you’re going to calm down this grebling child. You’d rather not leave them with any more trauma than you’ve already given them.
The blessings of Reth be upon you, my child
