Time Machine

You found a machine.

You're walking through a forest. You notice it's very foggy, but you ignore it and keep walking until you find a clearing where there's a machine. You don't know what it is or why it's there, but it's clearly not from your time.
You decide to approach, when a screen with three fields appears in front of you.
A cursor in the first field lights up, inviting you to enter a character or event. Below that, another field asks for a location, and a third for a date.
