Rany, I have an idea for the [generic disaster]. The device used to transport objects between Strings goes crazy, and is uncontrollable and it starts transporting random things across the other Strings. They send you in (Like you said), but after that, the machine breaks on your end and you can no longer get back. However, it is still transporting things in. There no communications with the lab, because for some reason the communication device isn't working correctly. You then have to gather technologies AND find a way to get back and you have to hop from String to String to get them. Meanwhile, your world and other Strings are falling apart. They are falling apart because, unknowingly, every time and object transports between Strings, it makes them a little more unstable. For the end, you have to find the source that caused the String transporter (Not named), which is a virus, and you have to shut up down. If you like the idea, send me a message and I'd be glad to give some not ideas
