Her team's traipsing through the jungles of Chult, chasing down their latest lead for the Shield Guardian's amulet (since the more they can bring to bear against Acererak, the better). Liliane is paying close attention to the geography, to help with returning to where they left the rowboats, when a giant snake with a mirror for a face appears in front of her. Her hand goes to her flail, but before she can otherwise react, it's on her. She flinches, and is elsewhere.
"They sound like it. I imagine they're even more so when they have goals other than 'catapult themselves on a dinosaur.'"
Pfft. "They've yet to try that particular combination, but - I have faith in their chances, even down one."
"It's only a matter of time till they try it! But your world sounds like it's in good hands. ...maybe not safe ones, but good ones."
"Yeah. Of course, it's still horribly dangerous and important and I'd like to get back and help given the consequences of failure, but - here needs help, too."
"We'll try and find a way to get you back as quick as we can, and we can swap: you helping our world for us helping yours."
Shortly afterwards, they translate out of realspace into the webway, the sky of stars replaced with glowing threadlike tunnels. They travel through it for a few days, before emerging.
The sky is lurid pinks and purples and ultraviolets, the stars blocked out by swirling mist of shining matter. A massive orb floats underneath them, black with long red veins and bruises stretching across it.
"Former heart of the Empire, current outskirt of the Eye of Terror." She's shielding her eyes, as if there was glare from a sun. "I wouldn't look to closely at it, it's not great for your health."
"The short version is something like this: have a big empire. A really big empire, full of people connected to the Warp. Have them want for nothing. Have them get bored. Really bored. Bored enough to start torture cults.
Have that gestate a god. Have that god tear screaming through the veil between the Warp and Realspace.
...and that's how you get the Eye of Terror. And the soul eating problem."
"That does not sound very fun at all. And, huh, I don't think that's how you get new gods in my plane, but I might be wrong."
"New gods aren't really a thing here, She Who Thirsts is sorta an exception? It had something do with emotions generated, I'm pretty sure. The Warp is basically made of emotions."
"There's myths of new gods happening, I don't know that it's happened in recorded history."
"Guess that's another difference between our worlds? She Who Thirsts' birth is in living memory, but only for very old people."
"Could be, yes. I wonder how it is that magic's so different between our worlds, it works more-or-less consistently across the planes around mine."
"Maybe some sort of... disjoint? in the planar system? I'm very much not an expert on these things."
"I think somewhat, the Outer Planes are more - different - than the Inner Planes, but it's... Not really distance? Or the distance is metaphorical."
"Considering how different our worlds are, a great metaphorical distance doesn't seem unlikely? But they're different enough that it could be something completely different."
"We're just going to have to be confused together then."
"We're making planetfall in 10 minutes," Jas says.
