But this place wasn’t just ruins.

Something is after you

There is something that follows you.

It moves through the darkness and never gives up.

Stay quiet. Move carefully.

Sometimes, you must fight back

You have the means to resist.
Running alone may not always be enough.
Opportunities are rare—but not impossible.
