Battle of Polis Massa

The Battle of Polis Massa was the final conflict in the Sith Empire Crusades, between the Sith Empire and the Mandalorian Federation Remnant.

Preparation
Prior to the inevitable battle, Raylen Eros traveled to the Galactic Archives on Ahch-To to potentially find a way of stopping the Sith's superweapon to no avail.

The Battle
In the early morning hours, the Sith Empire entered the Polis Massa system in a very quiet manner. Raylen Eros noticed their arrival and rushed to the war room along with his wife, his son, and Rian Jaxx. The last three remaining Mandalorian cruisers began attacking the Emperor's flagship, the Prometheus, under the direction of Admiral Klaue Klyde. They were destroyed in an instant and the occupants of the cruisers were subjected to an infinite Force Projection.

Once the Federation Navy was destroyed, Malgus and his Sith warriors entered the Polis Massa base. Annihilating everyone who stood in their way swiftly and silently, Malgus and his apprentice Vanitas entered the control room, taking Raylen, Julia, Rian, and Base Director Jor Rathe off guard. Rathe and Rian were the first to be killed by the Dark Lord. After their deaths, Malgus ordered Vanitas to retrieve the son of Raylen, as he was very strong in the Force. Julia objected to this and was killed by the Emperor. After Raylen Eros got one last look at his son, he spat in the face of Malgus and was knocked out.

Aftermath
Following the Battle, Vanitas fled from the Polis Massa system with young Jorel Eros to the planet of Ventos Prime, in an effort to raise the child to combat the newly self-appointed Sith Emperor. Malgus vowed to find his disgraced apprentice and destroy him and capture the boy. Raylen Eros was taken to the Sith Empire capital on the planet Dromund Kaas, where he was subjected to intense torture by the Emperor as punishment for not having his son.
