The two children were doing a bridge exercise.
Theanore had gotten her gymnastics skill two days ago, but her mother still insisted that they should practice it more. Apparently, if she got this skill high enough, she could do underwater dancing gracefully!
It was not a real skill, as far as Marinus was concerned. Every member of the merfolk could do it. But Esmer had shown the children her skill list and there it was, right beneath diving.
Diving was another skill that Esmer had Theanore practice.
She wanted to get the girl to learn underwater refuge for her level 11 level up. With level 10 reached, Theanore got a tribe of pixies to make things from the silk.
When she wasn't working on gymnastics or diving with Marinus, she enchanted the clothing.
The silk was so abundant that the pixies could barely catch up. A pixie was no bigger than a hamster, a regular sized one, but, unlike its cousin the fairy, it didn't have wings.
