Oh. So no information other than "run," which is looking like a bit of a candidate.

We could try firing on her, it might even work–

We should warn Melian, find out if she thinks she can handle Ungoliant....

I don't know that she'd be favorably inclined towards advice - or, really, not distracted by it -

She'd hate it. Coming from us especially. But the other option is to not warn her and I can't see that being any better!

If she's already working on something and we interrupt it - could tell Thingol, let him decide what to convey -

That works. He knows about magic, Melian must have told him what Ungoliant probably is, he'll know to be scared.

He does that.

Didn't answer, but I think that's the best we can do.

We could say that when Ungoliant makes her challenge, Melian can insist on allowing allies and we'll help. It's an option.

The obvious catch is I'm not sure what all we can do, and the less obvious one is that if Ungoliant is just an ordinary terrifying spider monster it's not obvious who we'd want to win.

Isn't it? 

If she gets the Silmaril, she either manages to eat it and there isn't a war or it's too indestructible and at least the war isn't made entirely of collateral damage.

Doriath falls.

You mean the Enemy's threat, or you think Ungoliant would kill them all on the way out?

The latter - why wouldn't she -

I was just thinking they're not what she's after and she didn't in Valinor—

Okay, if that's the risk we're definitely on Melian's side. Maitimo, this would be another good time to help out if you've got anything.

To distract her marginally, sure - does your mysterious trick I know nothing about not work on her -

It wouldn't– or, might.

I need to see her with the Sight. Did anyone use that while running or do we have to try to get closer?

No one did that.

Okay, then we need, she tries to stand and take off but winces and reconsiders, we need to send someone who hasn't broken anything. They can tell us if she's an Other, and if she's an Other she's got to be a demon.

And someone bounces what Ungoliant looks like by the Sight -

She looks more visible, is really all it takes. The exact details of the chitinous hide and barbed mandibles aren't exactly pleasant to look at, but what really matters is that she stands out instead of fading into the background.

She's an Other. So calling her name can get her attention, but we'd all be summoning a demon in at least the literal sense...
And even that's assuming Ungoliant is her name, and assuming it feels the same for Others as practitioners.

(Maitimo gets the description as "it might work but is separately a bad idea. Not that it'd be at all hard to put the explanation together.)

Then I can provide distractions.

If we can keep her in one place long enough, maybe we can light a ring of fire around her. And keep it in place somehow.

I don't like the odds but she's darkness so we need light.

Doesn't she eat light?

Yes.

It wouldn't shock me if a demon's weakness was also its favorite thing to destroy? Or maybe she's darkening instead of darkness. Either way this is less of a long shot than throwing things at her–

Nod. (And the osanwë impression of one.)

I bet if it's in Doriath Melian could keep a fire in the right place indefinitely. Probably wouldn't even need us, we could just pass it through Thingol. Problem is I doubt it'd be enough light to hold her for long and we don't have anything more permanent.
