Once the characters have both keys, they can decipher the map. The treasure is on the border of the universe on an asteroid that resembles a typical treasure island. In the map the exact coordinates of the treasure are noted. If you enter the course, there is an infinite duration.
Since it is extremely unlikely to travell on the border of the universe is, it is quite likely that it can be achieve within the Improbabilityzone. Within this zone, you can see everything that is unlikely, from flower pots to speaking whales. The room seems in all colors, gases flow into eddies and the ship is difficult to maneuver.
Only in the Improbabilityzone it is possible to program a course that leads directly to the border of the universe. If the course has been pragrammed and the FTL is started, the space ship is now a light year away from the asteroid belt at the border of the universe.
