Sony Online Entertainment announced today that the fifth expansion for the Star Wars Galaxies Trading Card Game is scheduled to launch on Dec. 15. The Nightsister's Revenge adds the new "Beast" trait, the "Agility" keyword, two new playable avatars and a new 10-scenario story arc.

Of course, no TCG expansion would be complete without loot cards. The Nightsister's Revenge adds more than 20 new loot cards to the mix, including two spires that are among the tallest player structures ever to appear in Star Wars Galaxies.
