Zeylin Coldhill

In life, Sir Zeylin Coldhill was the Grandmaster of the Silver Knights of Thassalus, Lord of Loc Arn, and champion of many tournaments. Most notably, he was the undefeated champion of the Grand Tournament of Erradan. He was known as a charming and handsome man, yet also sly and untrustworthy.
=== Summary ===
In 19.29, Sir Zeylin died while investigating rumours of rising undead in the Palewood. He made it all the way to Mortholme, before he and his knights were slain by a Black Legionnaire, for interfering. However, Zaikerik saw great potential in his soul, and offered the knight the chance to serve him, in return for power and glory in the afterlife. Zeylin accepted.
At the Grand Tournament of 20.15, the unstable necromancer Anovid Kilnegar summoned Sir Zeylin's ghost, who then brought an army of Zaikerik's undead to the city, in an attempt to weaken the city's defenses, and potentially capture the Queen. Sir Zeylin's pride was his downfall here, as he challenged the competitors to defeat him instead of focusing on his task. He was defeated by an Anonymous Knight, slain by beheading, and returned to the Spirit Realm. A Storm Dragon later helped defeat the undead army, and thus the attack was unsuccessful.
Zaikerik was irritated by Sir Zeylin's pride, arrogance, and recklessness, and as such punished his servant, by causing his spirit to be permanently headless. However, he also rewarded the knight by granting him a powerful suit of Black Legionnaire armour.
The very next year, Sir Zeylin collaborated with the Jailor, the undead King Eradall II, and the mortal cultist Sylomara Thornvale, to try again to take the city of Erradan. Though they were unsuccessful, due to the efforts of the Saviours, they did manage to weaken the city and distract the Dark Monks, allowing Zaikerik and Raven to destroy Haven.
Sir Zeylin was present when Ayla Vanderstone and Velkyn invaded Ravensroost. He was mostly oblivious of their presence though, and when Ravensroost went up in flames, he wisely left.
Sir Zeylin lead a small group of Black Legionnaires to attack the Black Monastery, while Gaius Lestrade was training there. Zaikerik had commanded him to free one of his former lieutenants, Arielle Dragonsbane. Though his legionnaires were killed, Sir Zeylin himself was able to breach the defenses and make his way to where Arielle was captive. However, rather than freeing her, he slew her, for he knew that if she were freed she would take his place at Zaikerik's side. Gaius Lestrade and the Faceless Guardian then confronted Sir Zeylin, and in a tense battle, managed to slay him with Absolution.
