Remember when everyone first met Worf? And it was INSANE because how could a KLINGON BE A FEDERATION OFFICER?? Neither do we, because that was a really, really long time ago! Also, because Worf became such an iconic character that now our brains forget that that was ever really a thing.
With the Alien Officer System, allied Alien Factions will send you a high ranking officer to act as liason! That officer's presence will, in theory, help strengthen the bond between humanity and their race through mutual dependence and understanding. In theory. Practically speaking, these alien officers will be able to do everything that Human officers can, but they’ll have crazy, unique race-specific skills and Traits! And we’ll be putting together tons of new alien officer-specific events for each alien race type.
