Concept: After reaching the time machine (wide teleport) you got in the right time but wrong place.
The place had a flat surface, at the end was a portal. You (marine) thought that would lead you to the right place. You enter the portal first, you arrive in a strange place and a lot of portals. Noir lime asked "Is everything okay?". Before you could anwser, the portal shut off, making you stuck. You find a pedastal, with a star shape carved into it. You know what this place is, the multiverse. You decided to enter the first portal.
Your first journey begins.
