Thousand Stars Access Authentication Information

Thousand Stars Access Authentication
Description	A mysterious card used to access an unknown facility. Its corner has been chipped away and the letters on it have become unrecognizable. But when you hold it under the light at a certain angle, you can see the faint letters that read "Thousand Stars." "Obviously this card was extremely valuable, but it was discarded like trash when someone lost interest... Sounds like something Herta would do."
