Currently I'm stuck up in next chapter but for now I want to show some small idea about Changelings. Their alphabet.
For now it looks pretty simple. Different letters, but that's all. Well, it's not quite true. There are Symbols. And they are often used to replace the words written with letters. Why? Symbols are using less space, sometimes faster to write, and some are fast to recognize. Few examples (there are more, much more of them).
You could ask: What Symbols and letters have in common? Letters of said word are written in Symbol. Okay, so again few examples. For start "zebra".
It looks easy, doesn't it? And all letters are in symbol as said. But it is weird why it's written from right to left. Does Changelings read from right to left? No. Symbols can be created from any side to any side. Let's look at sun.
Sooo, symbols can be written from left to right, up to down, right to left, down to up... And they can be rotated by 90 degrees clockwise too. And even worse, some lines, letters can be omitted during creation of symbol. It's making quite a feat deciphering them.
It's all for the moment, maybe I'll extend topic later, if you all will be interested. I'm not sure it'll be used in story later, just part of world building.
