Okay, I don't enjoy being openly second-guessed in my own plot. Especially when I feel ganged up on. Backseat driving and all.
I don't see anyone portraying Umbrals on this site except me. There's an experience I'm trying to deliver, I'm trying to distinguish this encounter from Mefpralphra's... and damn it, you know what kind of GM I am and how I'm pretty ruthless with the NPCs - I'm kind of hardcore. I still have make calls even though I may not enjoy every one of them. And then I have to stand by them; even though I'll admit to a dichtotomy between what I feel is important and what players actually care about. Suffice to say what I wrote wasn't necessary for the scenario, but it was written because it was part of what I thought this particular Umbral Elder could and would do. That includes Yukari's willpower being crushed almost effortlessly by a creature that's thousands of years old and populated by a collective of several thousands minds acting in concert; especially considering she's been left relatively pristine by her previous encounter with Mefpralphra; whereas in different ways Nyton and Tom have been toughened up on top of being the kind of player race that's actually more resistant to this: human.
Critique from Tom kind of worked because he is involved in the plot itself, though I would've prefered questioning my competency would've come through private channels. Because, openly like this, this is what it's been feeling like. I'm not closed to negative feedback... because it's frankly the only way I can improve things is by being told what works and what doesn't. But not like this.
So, kindly get off my case. If you feel compelled to apologize, don't. Just drop it. What I want now, on this issue, is silence. I talked it out with Doshii, and now I'm waiting for the contribution of two other people.
