The Others

The Others was a reference used by the twelve Iconians overseeing the invasion of the Milky Way in 2410 to a group responsible for saving them from their doom, when their homeworld, Iconia, suffered an orbital bombardment 200,000 years ago by an alliance of several species wich had rebelled against the Iconian Empire's rule. For the Iconians, the Others had died during the assault in order to save them. It was later discovered that these Others were actually a group of the Alpha Quadrant Alliance wich was sent back in time, intending to prevent any Iconian from escaping the orbital bombardment, meaning there would be no survivors to fight the Iconian War.

Origins
After being helped by the Others, the three Iconian sisters, M'Tara, L'Miren and T'Ket, alongside with other nine Iconians, hidden themselves from the rest of the galaxy for over 200,000 years, slowly rebuilding their once powerful and peaceful Iconian Empire. In the early 25th century, the Iconians return and launch their campaign of conquest through the Milky Way, thus leading to the Iconian War.

After six months of open conflict, the Iconians chose their last target, the Sol system. Members from all four quadrants of the galaxy were united striving for their freedom against the Iconian forces. During the battle, a Krenim ship designed to create a time portal arrived in the system. Their goal was to send a small group of ships back to ancient Iconia 200,000 years ago and eliminate any chance for the Iconians to escape their destruction. Only three ships made it, an Imperial Klingon Ship commanded by Captain Kagran, a Dominion Dreadnought carrying former Empress Sela of the Romulan Star Empire and another Alliance vessel.

Kagran's ship arrived two weeks earlier than the two other ships. Sela, the Alliance vessel's captain and four of his officers beamed down to the planet 2 hours before the bombardment. However, upon seeing the ancient Iconians peaceful nature, the team decide to help them instead of comitting genocide against innocent people. While the Iconians escape through a gateway, however, Sela changes her mind and start shooting them, killing two of the Iconians and wounding L'Miren's leg, and steals the Iconian's most valuable artifact, the World Heart, from L'Miren's hands. Kagran is able to stop her before she can finish the work, leaving twelve Iconians alive. Because of that treachery, one of the Iconians, T'Ket, swears that one day she would extinguise Sela's people. Realising she was the cause for the destruction of Romulus, an Iconian plot, she returns the World Heart to one of the Alliance officers and back to the future.

As they return, Kagran orders the Alliance fleet to stand down and one of the Alliance captains hail the Iconian flagship and shows the World Heart for them. Realising that they were the Others, L'Miren orders the Iconian forces to stand down, thus finishing one of the most devastating conflicts in all galactic history. The Alliance then returns the World Heart to the Iconians, wich return to their devastated homeworld in order to rebuild their civilization.
