The largest lake in the land!

It's a lake!
They are going to make her cross a lake!

Aloy feels herself dragged to the edge of the water and a Machine Station goes to work on her

She feels her legs pressed together and hears the sound of metal locking.

More of it covers her legs and below!

She can also feel ear plugs (of a sort) pressed onto her and the gas changes to a form of oxygen.

A metal arm grabs her by the waist and picks her up.

She feels herself drop and then every exposed part of her body feels wet!

She's dumped into the lake and the servos on her legs take over.

The Machines turned her legs into a robotic tail with fins and motors!

She can't help but 'swim' across through the water against her will!

The Machines even taunt her by showing her what happened to her as a replay in her visor- as it was all documented for posterity.

She's embarrassed, angry and scared- all at once!

This part of the journey is not fun and she wonders what sort of thing they will do to her next!
