Reborn in a Tabletop RPG RTR

Six people woke up simultaneously with the feel of cold concrete underneath them.
They were in a state of confusion, unsure of how they arrived there, with no memory of previous events.

They did share one thing in common, though. Their last memory was arriving at a friends house on earth to play a tabletop role-playing game.

In this game, you choose a race, class, and basic starting appearance, though no remembers the name of the game somehow.

After a moment they realized they were now the very imaginary characters that were going to play that day, down to the last detail.
