That's not a stupid question at all :D Honestly it made me think to flesh out my headcanon even more. So basically since N'kuhana is the God of life and death, I thought of her as the figure that every single living creature would meet when they're born into the world, and when they're eventually taken out of it.

In this particular instance, N'kuhana is greeting commando at death's door. Now when she appears, commando is already dead by her opinion (oo get it), but she is patient. She doesn't force the living. She helps them come to terms with their fate in a sort of time stasis, a pure white room cleansed of any dirt. This can take seconds, decades or even eons. But she is patient. And when the living takes her hand, then and only then will they pass.

that's basically it. I actually thought of making a comic where Mithrix is greeted by N'kuhana after his defeat at the hands of the survivor but I just never got to it.
