Death will personally see to nobody dying. That's interesting. It also means that, at least if she interprets this right, the whole "no death" clause hinges on Death sticking by his opinion that nobody should die.

And "the so called 'Dead' Arcana". So not dead, just gone, completely and absolutely ...by what standards? For this round? Out of reach of the Arcana?

How does an Arcanum met "so-called death"?

But for now, she's not asking any of those questions, in part because Death has addressed Maria directly.
