How does an assassin playing like he works for both sides, but really is just using them for the fact that both sides pay him sound to y'all?
Sounds like an interesting character that I'd like to see develop. Though given the royals on the White side telepathic and empathic abilities, it makes them hard to deceive.
Ember, I hope you don't mind my expressing opinions on "red" characters? This is an interesting concept. The only thing I would be wary of is ....
True, but what if he has the power to conceal himself in every way possible. Even his thoughts and emotions?
... If he is capable of concealing himself from every form of magical and non magical detection, what is to stop him sneaking in to both of our palaces, killing us both and taking over?
This is an example of an over-powered character, in my opinion.
He MUST have some weakness, some point of vulnerability.
Heck, my character is potentially the most powerful in the world and she has several serious weaknesses!
If I might offer a suggestion, perhaps he can conceal in every conceivable way, but only one at a time! In other words, he can be invisible, but can be detected magically, or he can hide from magic but can be seen with the naked eye. He can hide this thoughts from a telepath, or he can hide his emotions from an empath, but cannot do both at once.
This is just a suggestion, feel free to build on, dismantle, or disregard entirely...
