Behold, Artesia's little sister and 2nd in line to be the family head, Saylia Moonsoon. If it wasn't obvious, she works as a court jester for whatever king/queen or noble(s) requests her entertainment services.

However, she's also known to go off on her own to upturn any plots against her family, her liege, or her client(s), in that order of priority. Whether it be simple attempts to poison food or full on assassination plans, she'll root out the source and 'deal' with it in whatever way is necessary.

She also has a special knife/dagger that also works like a flute called a Kniflute, which she mainly uses for musical entertainment or more daring acts involving knives/daggers. It's also useful for bard-like magic to provide a magical form of entertainment, which she also uses in her little plot uprooting escapades if simply stabbing them isn't necessary or allowed.

Her mask functions the same way that Artesia's does, though it isn't as useful since she can't use it as a magic focus since her Kniflute fulfils that role already, making it only useful if she is separated from her Kniflute, which is a rare occurrence anyway. However, if Artesia wore it, it would be no different to wearing her own mask, it'd just be a bit more difficult since it's smaller and is stitched into the rest of the jester hat.

Here's a few extra, more specific details about her:

She's 22 years old, 6'2", is a bit more tanned than Artesia because she gets out a whole lot more, and (despite her line of work involving lots of movement) eats a noticeable amount more than Artesia, more than she should for that matter, so no abs, only tummy.
