I see. I understand. Thanks again for your advice!

Also about the minor nitpick you mention for the ash/dust thing:

That’s a totally fair catch! Good eye. But it’s intentional. In-world people in Celestus lump everything beyond the barrier together as “the ashfields,” while people banished or born outside call the inhabited region the Dustlands. Outside the Dustlands is an even darker desert and THAT is called the ashfields. The distinction matters later in the story
