Unexpected. Snag the shade. But her goal is served. She pushes the debris out of the way, and evaluates the remnants of the situation.

There is very little remaining situation. Contessa is gone and everyone else dead, and now that everything is demolished she can see she was in a temporary mockup of a Cauldron facility rather than their real base. If the explosives didn't already give it away.

That's a pity. Probably no detectable residue of the gate Contessa used, hints as to where the real thing is?

Not after it's closed. She can at least find out whether it's on the same earth by making a portal and checking whether all the familiar earths are accounted for, but there's no hint of Contessa's door.

Are there any familiar Earths unaccounted?

Doesn't look like it. Earth Bet is the easiest to reach from here, which means this is either Cauldron's earth or Aleph, and Aleph is relatively recognizable. So she's probably on the right planet.

An entire Earth is still a lot of room to hide. Not likely to be near the sacrificial decoy base, though. Time to go flying.

This world is sparsely populated. Her best flyers can get her high enough to see that there are a few agrarian villages dotted around the countryside, but nothing that looks like a Cauldron.

Any Thinker-ish cues?

She has a lot of Hunch duplicates. Eventually she can start narrowing the location down without an intolerably high number of false trails. Turns out it's near Africa's western coast. Hard to say which country since this Earth doesn't come with color-coded national borders.

Bet doesn't color-code either. But she can get to Africa and take a look.

Africa in Bet doesn't have many surviving nations anyway. This world has a low enough population that they might have just never bothered with the concept. For her purposes, of course, all that matters is Cauldron or Not Cauldron.

There's a very modern-looking building right where her thinkers told her it should be. It's enormous.

Looks like Cauldron to her. And big enough to be hiding something. Probably doesn't have any doors, given their gateway ability. But then, she doesn't strictly need doors either.

There are doors. Not that they see a lot of use, but they exist.

Her guesses have proven accurate so far. Now they're saying that she needs to go down.

Down it is.

This is fairly thoroughly hostile territory. She should be prepared for attack. That means Crawler, and she doesn't care if interior walls don't survive her passage.

Or floors, apparently.

Eventually she'll find her way to a long narrow shaft. Probably there are elevators or something, but for her purposes all that matters is that it's a way down. 

She squeezes in and drops.

There's no sign of, as it happens, anyone. They must have guessed her path and cleared it.

Following the obvious route once she's down, it's pretty unmistakeable that she's here. It's a vast cavern; presumably there are at least three sides but she can only see the one. All of it is filled with body parts. Limbs, faces, miscellaneous flesh. All of it could be human if not for the dull silver color. By all rights it ought to look disturbing, but there's a sort of unearthly beauty to it. It's not obvious how deep the roots of this garden go, except that it's deep enough for Cauldron to construct walkways over and across instead of clearing a way through.

Her vision has more dimensions than most people's. She can see shades, sort of. Ghostly figures superimposed on the gray flesh, playing multidimensional charades. Trying to collect one fails just as trying to collect Noelle's power did.

Incredible. What it must be, to have such power at your beck and call. To subsume entire timelines and bend them to your will.

This. This is what she wants to be when she grows up. And fortunately for her, there's a job opening.

It's too dead to offer to hire her.

A voice pipes out of an apparently-existent speaker. "We both know it's useless to you. The best you can do is let us exploit it and avoid killing enough parahumans that we write you off as a loss."

This one is dead. Scion is not.

"I just wanted to see it. Now I have."

"We'll refrain from the death threats, then." One of their portals opens in front of her, leading back to Bet.

No reason not to take it. Easier than getting up to ground level on her own.

And this way they don't have a hole through their dimension. It's a win-win.

So now that she's back, she needs to find Scion. Easier said than done, it's not as though he keeps a schedule.
