Well, while Aureia asked about the fire, Mori went about her way finding things to set up a small fire pit.  Some small stones to make the outline.... Some good sticks to start the kindling, dry wood and some other small things.  They didn't need to much to get food cooking. It's not like she needed to eat much herself.  Considering her borrowed body, it wouldn't be a bad idea to take in a little food too.  

Still, getting these resources to cook was a bit of a pain.  The best she could do was gather stuff off the forest floor.  It'd be much easier with tools of some sort. "Gah, I wish I had an axe or something of the sort."  A dagger would make most of the work from here much easier.  She could cut sticks into poles to cook meat or cutting the meat itself.  Then a thought dawned on her.  She took the body of a soldier... So maybe she had a dagger on her!  Hah!  Blessed was her day!

A quick look would tell her that... Yes! Indeed she had a dagger on her! It looked rather clean too, despite all the gooze and ooze from the transformation.  "Aha! Behold, I have a dagger!"  The Chief of the Underworld exclaimed as she held the dagger high for all to see, before calmly putting it back in place and gathering the rest of the lumber and stones she needed and taking them back to where they would set up camp.  She set the circles up in a ring and expertly put the kindling inside, waiting for fire.  She took the next bit of time to take some rather long sticks she found and started to use the dagger to cut them into spears to cook the meat with so one didn't need to hold their arms dangerously over the fire.  After all, her flesh was rather weak to a fire like such.  "You all can praise me now~"

She seemed like she... rather than want... Needed the praise.  Perhaps she was a slight bit coddled by her servants in the underworld that priased her for all her judgement calls and successes... Probably even her failures.
