The idea here is to make these people have to hide at all times, hence the castle for them all to stay in.

Dizzy: I like the birthmark, but is there any way we can expand on it? Perhaps it sits somewhere harder to hide or she cant cast any illusions if it is cover it up? Audio visual illusions can be the most powerful if done right so I want to make the cost appropriate

Gravislayer: are you willing to make the empowered appearance his default? If not just his eyes being stuck in the dark setting. It is a good power, but having his mark only present when he uses his power makes it too easy to hide. 

Blacksam: Cyclops needs a much heavier downside to his powers or a reduction of his power. His beams are strong enough to destroy a fortress but he can control the width height and intensity? It's force but can bank a dozen times? Able to put a hole on a wall or a pinhole in a coin 2000 feet away? I need some consistency here on what his powers are since he basically has visor on/visor off.

He doesn't have the adjusting goggles visor

At best you have a single pressed lense of ruby dust glass

And he would probably have to sleep in a ruby lined iron mask to not take out half the castle waking up from a dead sleep in the middle of the night.

Zombie: If her skin is so pale as a reflection of her power, I'm okay with it. otherwise I need a downside to mark her as cursed with power.
