Aether sensing: I'm absolutely fine with this! I can't imagine her aether being anything other than Standard Human, maybe a little bit more than usual. What's unusual is there's the aether of twelve other beings inside her, which are all various degrees of POWER (aside from one that's actually kinda weak). Check her Personas page on her journal for an idea on those, they're all various elementally aligned.

The Echo: I am also fine with this, though I apologise for her sad backstory. P3P is a Happy Story honest.....
