Tholian Incursion

The  (also called Tholian Invasion) is a level-50 adventure zone on the class-Y planet Nukara Prime in the Nukara System which is located in the Boreth Sector of the Beta Quadrant. It requires players of all factions to counter an invasion attempt by the Tholian Assembly and contains several missions of different difficulties separated into an exterior and an interior subzone. The hostile environment of Nukara Prime also requires the player to wear an Environmental Suit.

Missions
Leading new captains to the Nukara System, the mission is given as soon as level 50 players enter the Boreth or surrounding sectors.

Interior and Exterior missions of the Tholian Incursion reward varying amounts of Nukara Marks, a Tholian Equipment Requisition, and have varying cooldowns based on difficulty. While the Bonus Marks Event is active, the amount of marks rewarded by these missions is increased. Both [Hard] missions are accessed via the PvE Queue.

Only one [Zone Wide] mission is available at a time, but it has no cooldown while it is available.
