[Third Person POV],
Adara's request of Elsie is actually quite straightforward.
There was a vast area of uninhabited land in front of Adara and all around her.
Adara reasoned that she should gather her friend and some of the other earth mages in the group behind her to construct a shelter as it didn't appear that any monsters were nearby.
All Elsie and a few other earth mages needed to do was to construct the various structures that would serve as their temporary home by manipulating the earth between them.
Adara thought the idea was a good one, but she decided to get the commander's opinion first. After getting the commander's enthusiastic support, Adara decided to act on her plan right away.
Adara first got Elsie to try creating a slightly hut-like house before she called the others in the crowd who could also manipulate earth like Elsie.
