@queentzeI've notices something reading Tut's history, and I know you were talking to Angel in private about it, but I know he wouldn't have accepted had he noticed what I have.
the body Tutan inhabited was immortal but he would remain an immortal child until his mother died, and she would only die if the baby was harmedThis particular statement has huge issues. Allow me to be more specific.
If the body Tutan inhabited was immortal then that means he can't be harmed.Seems pretty flawed right off the bat
until his mother diedThis seems like a redeeming quality.
until
and she would only die if the baby was harmedIf the baby is immortal it can't be harmed, the clause being he loses the immortality if his mother dies, which seems broken, but in a non broken way.
The issue, being, that his mother can't die, unless he's harmed. How can he be harmed if he's immortal? He can't be. Which means, she too, is immortal.
Now, excusing the fact that this was
hidden in the history, instead of being listed in the powers as well, it's too OP of an ability for any one character. Even the space entity that is Umbra can be injured and/or killed. And no, the obsidian thing doesn't count in my eyes, because kryptonite weaknesses are nothing more than cop-outs. Not everyone will have access to it, in fact, it's likely nobody will.
Edit: It's been brought to attention that there's another flaw.
Egress: When No Name is given this name she becomes the avatar of spatial movement for her master. She embodies the power to open and close portals to anywhere she has recently seen, thy details for her portals must be accurate or else she might end up in another dimension no matter how close it is to her original. Her power works best when she has something Specific to call upon, maybe a ditch n the road or a monument that has odd color, details help keep her in this dimensions and help her go to the correct place. In order to use this ability she has to sacrifice on of her limbs to make the portals, what is left over is a useless ghostly arm, leg, head, torso, this is Tutan's term.
With the limit stated, there's two issues. One directly correlated to what I had pointed out: If she's immortal because the child is, she can't lose any limbs, as that would cause a paradox. Second, it's stated she has to sacrifice a limb, and then in the examples you've included her head and torso, neither of which are limbs, only legs/arms have that classification, so she would only get to use it four times, and if she did so even once, and it has the limit stated, the paradox would cause neither of them to be immortal, as the history claims them to be.
