The mirror opens up on a partially-buried machine - the unfinished ANIMa Creche, for those who remember it.

Anna dusts the snow off of it and runs a diagnostic, frowning.

Fortunately, at the end of it, she nods. Lucky her, it still works, mostly - most of the bugs are things becoming physically disconnected, which she fixes.

She then takes a small jar of what appears to be sand from her pocket and -

Ah. It is sand, from the wild places. Because she spills it around herself in a circle, resulting in a small barracks springing up around her and, more importantly, the device.

It's layout is roughly hexagonal. The final part is a large door - she unbars it, exits, and dusts off her hands.

Then notices the mirror, looks around furtively, then sighs. "Just thought I'd check up on Creche Alpha, make sure it was safe," she says to the Mirror.
