Captains Log, Stardate 44093.7
"The USS Boadicea has picked up a distress call from the Deep Space K-10 science station and we are responding to the incident".
The PC's arrive to find that the stations crew has been wiped out and the station itself has suffered lots of damage. The crew then discover on the local planets surface (the last known location of a research team) an Iconian gateway. This leads to the opposite side of the galaxy/Federation space.
It appears that a hostile alien race attacked the station when one of the scientists opened the gateway and travelled the huge distance to the alien homeworld.
Any further ideas? Are Iconian gateways used for time travelling or "galaxy-hopping"? The science station orbits a recently discovered Iconian city underground. The planets surface is like that of (old) Mars, thus requiring EVA suits.
