Radia's domain could be considered to be the most calm out of all they elementals the siblings had previously visited.
The landscape, the atmosphere, the wildlife and vegetation. Everything was just so calm and serene.
She showed them fields of white and golden flowers, had them interact with the animals which were very friendly, they even took a swim in the river's.
It was all so chill, and the siblings appreciated that greatly. So when their stay with her came to and end, they were both reluctant to leave.
Radia saw that and the motherly smile on her face became gentler. She lightly patted their heads.
"Don't worry, you two can come and visit again anytime." They both didn't resist her touch and nodded.
"Um." Seeing that they about ready to go, Teran bowed towards Radia and was about to leave.
