- — To Vivian
Thassarian is the first death knight to join the Alliance. As a young man, he joined the Lordaeron army hoping to follow in his father's footsteps. Thassarian followed Prince Arthas on his expedition to Northrend, where he was slain and reanimated by the Scourge. He was forced to kill his own mother to prove his loyalty and took part in the scourging of Lordaeron and Quel'Thalas. One of the few death knights of Acherus who maintained a genuine sense of honor and brotherhood, Thassarian developed a strong bond with the elf Koltira Deathweaver despite being enemies in life, considering themselves brothers in death.
During the Battle for Light's Hope Chapel, he was freed from the Lich King's control along with many other death knights and joined the newly-formed Knights of the Ebon Blade under Highlord Darion Mograine. Thassarian then traveled to Stormwind to serve King Varian and became the first death knight to rejoin the Alliance. He reunited with his sister Leryssa while fighting in the War against the Lich King. After the war, Thassarian remained a loyal soldier to his king while also maintaining his friendship with Koltira, even when they were forced to confront each other during the Battle for Andorhal.
Before the coming of the Scourge, Thassarian was a simply farm boy being trained by his father, who was a farmer but also a soldier. His father taught him a lesson that he would follow for the rest of his life If soldiers don't follow orders, defeat is sure to follow. After the death of his father (presumably by the orcs of the Second War) Thassarian became the man of the house and watched over the farm, his mother Vivian, and his sister Leryssa. When word of the plague reached them, Thassarian became more vigilant over his home and stayed up almost every night. His sister passed the plague off as simple rumors. One day he decided to fulfill his dream and follow in his father's footsteps. He enlisted in a barracks nearby and went to train with his family friend William Allerton under a commander known as Sergeant Yuval.
One day a promotion was offered to the best combatant in a melee and Thassarian wanted to win it badly. After defeating three combatants, the fourth one threw a dagger at Thassarian's head. Luckily it hit him with the hilt. After the battle, Yuval approached Thassarian to tell him that he should forget about rising through the ranks and be proud to be a simple skilled soldier that wins battles. While this was hard to bear, he remembered what his father had told him. One day, William came rushing with an urgent message that the prince wanted every available soldier to join him in a hunt. Thassarian accepted but his mother and sister knew that this would be the last time they would see each other. After drying her tears, Vivian gave Thassarian an amulet which used to belong to his father as her blessing.
He later traveled with and the rest of the 1st Legion to Northrend to hunt . When Arthas and went missing, he went to search for them alone. He discovered Frostmourne Cavern, where he found Falric. Falric, already converted to a Death Knight by Arthas, slew Thassarian, and thus began his unlife as a death knight.
Thassarian returned to Lordaeron with Arthas and assisted in the massacre of its citizens. Arthas forced him to slay his mother, , to prove his loyalty. This horrific event continued to haunt him, and it remained, perhaps, his last scrap of humanity for some time. After the death of Vivian, Thassarian tossed the amulet she gave him. William survived the massacre and retrieved the amulet, after this he left Lordaeron.
Arthas' assault on Quel'Thalas introduced Thassarian to the high elves and his brother, , at An'owyn, where he pursued the mooncrystal to open the second moongate and proceed with their attack. Thassarian nearly killed Faltora, but, upon remembering his mother, he decided to show a moment of mercy. He returned to Arthas with the mooncrystal that he recovered. Koltira later confronted Thassarian and questioned why he didn't murder his brother, hoping to convince him to regain his humanity. This attempt failed, and Thassarian killed Koltira, who was returned to undeath as another death knight. Koltira and Thassarian developed a significant friendship that lasts to this day.
Years later, after the Lich King had awoken the ordered his death knights under the leadership of to attack Light's Hope Chapel using the necropolis Acherus with the goal of raising the thousand or so Alliance soldiers buried beneath it to bolster the ranks of the Scourge and deal a significant blow to the Argent Dawn. Thassarian, Koltira and Orbaz Bloodbane were stationed at Acherus: The Ebon Hold. Their first mission was to go behind enemy lines and find out what they could about the Crimson Dawn. During the process Koltira got captured and Thassarian was willing to break the Scourge code concerning the weak to free him.
The attack on Light's Hope Chapel ended with a defeat for the death knights. Many of the family of the death knights were buried at Light's Hope Chapel, and the spirits of their relatives rose to convince them to lay down their weapons. Thassarian was convinced by his father, , to stand down. Mograine declared the independence of the Knights of the Ebon Blade. Thassarian traveled to Stormwind and met with who accepted the Knights of Ebon Blade as allies and readmitted its members as members of the Alliance. After this, he went to the Blue Recluse for a drink. He chose this place because he used to come here for the great food, drinks and conversation. He started such a conversation with the innkeeper Steven Lohan when he ordered a mug of ale. Steven told him he heard of the king's announcement and asked him what he'll do when the Lich King is dead. When Steven asked him if he'll return to his family, Thassarian simply said he had no family.

After joining the Alliance he traveled to Northrend and enlisted in with the Valiance Expedition. There at first he had to kill random Scourge in the area but later he was called to return to the Valliance Keep, where Counselor Talbot made him the leader of Unit S and under orders he marched to Wailing Ziggurat to dispose of it and use the Scourge technology against the Lich King. When Unit S approached their destination, they got attacked by terrible beasts. During the battle, he raised a skeletal warrior, naming him Lurid. Thassarian thought why would Talbot sent the Unit to meet their death. They eventually discovered that one of the soldiers in the unit was actually a spy for the Cult of the Damned. Only two men are known to have survived from Unit S. Thassarian and Lurid continued to the ziggurat. He found (in-game with the help of an adventurer) Tanathal's phylactery and started to interrogate him and the High Deathpriest Isidorus. After getting what he wanted, he traveled to Naxxanar, where he killed Luthion the Vile. Finally, he confronted Counselor Talbot who was truly Prince Valanar. Atop of Naxxanar, Prince Valanar was speaking with the projection of the Lich King and was about to give him General Arlos and Leryssa. After a fierce battle, Thassarian defeated Valanar and rescued his sister and the general. After this, he said farewell to his sister and promised her that he will return to her once his task is done.
After his victory and rescuing his sister in Borean Tundra, he traveled to Icecrown Citadel on the The Skybreaker where he seeks to further damage the Scourge. Being a former scourge minion, he knows many things about the Scourge and sends random soldiers to gather information about the cult, find flesh giant spines, neutralizing plague cauldrons and kill important Scourge members. He later appears in the Cathedral of Darkness to help Tirion Fordring when his cover is blown. Both of them and their allies fled in time. Thassarian regrets having to let the Lich King live in his weakened state.
