Jykira

One of the domesticated animals within the primary setting. The Jykira serves sort of the dog role in that it is a very common pet and also used by law enforcement and hunters. You may see a few of them in backgrounds in the VN, but more likely in the other projects like comics and stories.

Zy-Karo

Zy-Karo are the primary method of long distance communication within the Zhu Empire. They are small discs made out of various types of local stone that can serve as energy conduits (the more complex ones using higher quality/rarer stone). It is activated by the user connecting their own internal energy to the disc which fills the center and illuminates the carvings. from there it can access any other Zy-Karo with an energy signature that the user is familiar with this is normally done by the users energy manipulation but some can be built to allow users to manually scroll through on more advanced ones.  While these are located across all of Zhu society they are not mass produced in factories, which each one hand made by a group of craftsmen specializing in chi works. This manner of creating them means more advanced and larger ones can be hard to replace if they become broken or damaged. And outside of nobility it is normally weeks before someone can get a new Zy-Karo.

Will skip the concept for this one for the time being, and give her brief bio. Not as indepth as some of the other ones but that is because of her role in the story.  

The woman known as The Spider was once a promising fighter in Zhu society, seen as someone who would one day becoming a legendary martial artist due to her unique abilities and skills.  But following problems in her life she turned away from society and became a deadly fighter feared in distant lands.  No one knows what exactly she was doing in her absence, but the woman that came back was changed and beneath her polite actions were always sinister undertones.  She hangs around high society once more, but many feel she is plotting something and all fear the venom that her name implies.
