Please see the disclaimer.

I have mentioned the term “Yzena” a few times, so I should probably tell my readers what it is.

As I said before, I have several ideas that I might turn into a business. When I first got those ideas, I came up with a name that I reserved so that I could use it. That name was Yzena.

In other words, Yzena is the name of the business that I will use to commercialize my ideas.
