Several options. One fell swoop while I'm holding infinity stones, might not work on anybody who didn't wind up in Mandos or something. Waiting longer, next spell being resurrection. That I'd probably do anyway for future and non-Ardan dead people. I occasionally fondly consider 'bullying Mandos into handling it' but it's probably a bad call.
Although if I'm going to do it anyway, 'immediately after killing another Vala, holding the method of execution' would be the time.
I do sort of wonder if I should expect Eru to show up at some point in the proceedings, and while I am reasonably confident in infinity stone versus Vala I am not nearly so in infinity stone versus Eru.
Yeah, anything anywhere which is really omnipotent is plainly not a good guy. I did not express this opinion to the converted orcs. Eru's motivations are opaque to me.
Wouldn't he know whether his grace and his interest in assigning me missions were in play?
Yeah, I don't know. I may just evacuate the universe if he shows up and isn't saying 'congratulations, that was swell'.
Well, then what I can do is a little constrained because that supposes he can prevent me and the Tesseract both from moving stuff around and I am staying put until he decides I can go.
Major considerations against are that the move might be toxic to Ainur and might kill magic music. Once I can get out I can test my looping songs before I bring everything along with me. I am out of specific Maiar I am definitely willing to kill, alas.
Yeah, but I'd have to go hunt one down. And the nuke might have shortened the supply.
I promised not to kill her once I take over the world. I suppose she might volunteer; her priority seems to be not dying in her fated manner.
And she goes and has a fly and then pops back in the hole.
