Well I have had several season endings now and I loved most of them more than the season openers. My favorite to date was a real mind bender.

The players had to go back in time on the USS Asimov (constitution refit used as a museum around Alpha Centauri which they had to get fully running in secret and then make off with) to thwart the plans of a race not unlike the shadows who had sent agents from the future to destroy key people and places so that the "Shadows" could win their war with the governments of the Alpha and Beta quadrants. The players succeeded, eventually, and after sending the Asimov and thier wounded back to the proper time they hijacked a K'tinga to finish the job on a rogue planet that was temporaly out of phase where an allied races colony ship had crashed long ago. the allied race protected a much more valuable ally who the players awakened. The agents of the "shadows" had followed of course and an epic ground and space battle ensued that ended with the great enemy defeated by the slimmest of margins and after several comrade NPCs as well as one PC had given their lives for victory. The conclusion occured when the crew limped back to theri proper time, on a ruined K'tinga, and the "Shadow War" was over. Time had been altered slightly, because I kept track of their moves and actions, in reference to what is canon and what has happened in between cannon timelines and my setting. They were heroes, but they could never really tell anyone cause noone really remembers things the same way anymore.

It was action, it was drama, it was horror and sometimes it was comedy. But as the ending came and went everyone looked like they had just gotten off a roller coaster as they looked at me and asked when the next season began.
