Update and info

About "Twishade rising", you can view 2 different versions of the first part of the comic versions of it. Also, it has been renamed "Mysterious Umbras". Here are the names of the chapters planned for it:
Chapter 1 - Jade
Twilight finds an orb. A few seconds later, Jade the warm-hearted umbral pony appears.
Chapter 2 - A second coming
The king of umbral creatures returns, and what he does shocks Jade.
Chapter 3 - Brightening
Chapter 4 - Into darkness
Things take a bad turn as Obsidia, the king of umbral creatures, causes more trouble.
Then there's the epilogue.

Note: Jade's name was inspired by a name in this MLP name generator.
