Hogrum Chalk

Hogrum Chalk was a Force-sensitive Human male who served Emperor Roan Fel until Fel's death in 138 ABY. Originally one of the Emperor's Imperial Knights, Chalk was maimed in an accident and consequently fitted with a cybernetic suit of life-preserving cyborg armor. He afterward left active service as an Imperial Knight and became the order's master armorer; in his new post, Chalk crafted the armor worn by his fellow Knights. Before 137 ABY, Elliah Fel—Chalk's sister and the Emperor's wife—was killed by the rogue Imperial Knight Eshkar Niin. Following his sister's death, Chalk remained close with his niece, Princess Marasiah Fel. However, he betrayed her father and became a spy in the employ of Grand Moff Morlish Veed. The Grand Moff was an officer in the Sith Lord Darth Krayt's Galactic Empire, an organization opposed by Fel's Empire-in-exile in the Second Imperial Civil War.

In 137 ABY, Chalk was with Fel's forces on the fortress world of Bastion, and he constructed a suit of life-preserving armor for Azlyn Rae, an Imperial Knight who had been gravely injured during a battle on the planet Had Abbadon. When the Emperor soon after went to the planet Agamar to negotiate an alliance with the Jedi Order, Chalk informed Veed of the meeting's location. The Emperor was subsequently attacked by a Sith–Imperial strike force put together by the Grand Moff, but he managed to escape Agamar with his life. Fel remained unaware of Chalk's betrayal and appointed him as the Director of Imperial Intelligence, which gave Chalk access to Imperial secrets, some of which he passed on to Veed. When an Imperial frigate captured the Sith Lady Darth Maladi, Chalk had her imprisoned on Bastion and brought Fel to see her after she, in an apparently crazed state, requested an audience with the Emperor.

Maladi claimed to no longer serve Darth Krayt and offered to create a deadly pathogen that Fel could use against the Dark Lord—albeit with high civilian casualties—and Chalk urged Fel to accept her offer. When Krayt unleashed his devastating Sith trooper army on the Empire-in-exile and its allies during an evacuation of the Jedi's Hidden Temple, Chalk reiterated his advice, and the Emperor deferred to his wisdom. During an attack on Krayt's throneworld of Coruscant, Fel prepared to unleash the pathogen onto the enemy capital, but he was halted and killed by the Imperial Knight Antares Draco, who had sworn an oath to end his Emperor's life if Fel ever succumbed to the dark side of the Force. The allies nevertheless won the battle and consequently the war, and at Fel's funeral, Chalk delivered a eulogy and announced that the galaxy would be unified under a new Galactic Federation Triumvirate.
