Attack on Krall's base

The Attack on Krall's Base was an attack by Jaylah and members of the crew of the USS Enterprise on Krall's operations base to rescue most of the Enterprise crew who had been captured by Krall.

Prelude
In 2164, the USS Franklin (NX-326), a ship commanded by Captain Balthazar Edison, a former officer of the United Earth Military, experienced wormhole displacement and crashed on the planet Altamid located in the Necro Cloud. Only Edison, Jessica Wolff, and Anderson Le survived the crash. Though the Franklin was intact, the three were unable to repair the ship and all distress calls went unanswered. The three survivors came to believe that the United Federation of Planets had abandoned them to their fates and were consumed with rage to the point of desiring revenge against the Federation. The three were able to locate energy transference technology left behind by the Ancient Ones, the previous inhabitants of the planet that would enable them to extend their lifespans by draining the life out of other beings. They also located sophisticated mining technology and a drone workforce that they repurposed for their own uses.

The three Franklin survivors, renaming themselves Krall, Kalara, and Manas ambushed ships and captured their inhabitants to use as a source of energy to drain. As a result, the three lost their Human appearances completely and stopped speaking English. Learning of a weapon called the Abronath created by the Ancient Ones, Krall led a search for "lifetimes" for the two halves, eventually locating one half of the weapon.

In 2263, using a captured Magellan probe, Krall hacks the database of Starbase Yorktown and learns that the second half of the Abronath is on the USS Enterprise (NCC-1701 alternate reality). Krall sends Kalara to lure the Enterprise to Altamid where his forces attack and destroy the starship. During the battle, Krall manages to capture most of the crew and takes them to his base where he forces Ensign Syl to give up the second half of the Abronath which had been hidden in her head by Enterprise Captain.

After landing on the planet, meets Jaylah, an escapee from Krall's base who had located and begun repairs on the Franklin. With the aid of Jaylah, Scott is able to rescue, , Kirk and , the latter two of whom had used the scanners in the Enterprise's wrecked saucer section to track a call from Kalara to Krall's base. The crew is able to use the Franklin's scanners to track a vokaya amulet Spock had given to Lieutenant to confirm the crew's presence at Krall's base, but are unable to beam them out due to geological interference. After learning of Jaylah's previous imprisonment in the base, Scott convinces her to help them and she points the crew towards a tunnel leading in and out. The crew devises a plan where Kirk, riding a BX-70 motorcycle from the Franklin enhanced with Jaylah's technology, creates a distraction while Jaylah, Spock and McCoy use pulse beacons to beam the crew out twenty at a time to the Franklin.

Battle
Riding the BX-70 motorcycle, and Jaylah beam in near the tunnel to Krall's operations base and Jaylah dismounts once they near the end of the tunnel. As Kirk continues into the base, Jaylah activates a pulse beacon, enabling and  to beam directly into the base. Kirk drives directly at Krall and Manas, enabling to escape Krall's grip in the distraction. Krall and Manas discover that Kirk has deployed many holographic versions of himself around the area, taking on the Swarm drones. Rather than waste time, Manas tells Krall to launch while he deals with the Starfleet officers.

Jaylah directs McCoy and Spock to the holding pen for the captured Enterprise crew before laying down covering fire for Kirk with a rifle. Spock and McCoy release the trapped crew only to have inform them that Uhura has been taken elsewhere by Krall. Spock goes to find Uhura while McCoy and Sulu use pulse beacons to enable and  to beam the crew to the Franklin twenty at a time.

As the crew beams to the Franklin in groups, Spock searches for Uhura only to be ambushed by two drones. Spock kills one and is saved from the other by Uhura. The two then join the last group preparing to beam out which McCoy refuses to let leave until Spock and Uhura are with them. The two reach the group, but the transporter still needs ten seconds to recharge and they are surrounded by drones who attempt to kill them before they can beam out. To protect the last group, Kirk deploys one of Jaylah's traps from his motorcycle which creates an impenetrable wall that shields them long enough for Chekov and Scott to beam them to the Franklin, leaving only Kirk and Jaylah in Krall's base.

While Jaylah lays down covering fire, she is attacked by Manas and they engage in hand-to-hand combat with Jaylah losing her pulse beacon in the process. Jaylah and Manas fight through the structure Jaylah had been sniping from, but are unable to defeat each other. As most of the crew is beamed out, Jaylah returns to the roof in search of her pulse beacon.

On the roof, Manas manages to reach the beacon first and tosses it off the roof, taunting Jaylah that the crew will abandon her. Seeing Jaylah's predicament, Kirk circles the structure on his motorcycle as Jaylah and Manas fight. Kirk activates his pulse beacon and as he starts to beam out, yells out to Jaylah before driving his motorcycle off a ramp into the air. Seizing her chance, Jaylah throws herself and Manas off the structure and is caught by Kirk as he's beamed out, resulting in both Kirk and Jaylah safely beaming to the Franklin. While Kirk saves Jaylah, Manas falls from the structure to his death on the ground below. 

Aftermath
While the Enterprise crew is successfully rescued, Krall and his Swarm ships launch not long after they reach the Franklin. Knowing that they intend to attack Starbase Yorktown and potentially use it as a platform to destroy the rest of the United Federation of Planets, the Enterprise crew repairs the Franklin and uses it to follow the Swarm to Starbase Yorktown.
