Cyril has a not-so-secret crush on Hannah. Cyril's parents abandoned him in a python-infested desert and replaced him with a zombie . This is shown in comic #44. He still has nightmares about it. It also showed Day]] comic.
Cyril also ate a Nature's Gift (dubbed "Flower") in comic #253, in which he has been developing Magic Powers. He has denied this in his mind(#280), where the Nature's Gift has told him that he is now a wizard.
Cyril also becomes remarkably more insightful when he begins to fear that his life is coming towards an end
("Imminent death makes me verbose.") such as in comic #110.
He eventually finds himself sitting in the middle of the Corruption with a soldier's uniform on and no memory of what's happened.
When Cyril dies, like all other NPC s, he is taken to the Clouds by an angel in the Column O' Light (due to NPC s not being important enough to take to Heaven since they respawn in the morning). He has died an unknown amount of times so far, being seen dying in comics #16 and #173. It is also mentioned during comic #436 that, during the battle with Xylan's minions, he kept dying "every ten seconds."
When Cyril died for the first time in comic #16 , he was given a Cellphone by Remmy to keep him updated on what's happening below the clouds. When he died the second time, before he went to the Clouds , Hannah sprinkled some of Aley's fairy dust on him to resurrect him.
Starting in comic #56 , Cyril gets a fear of water, as they almost drown by going down a shaft.
Cyril's favorite color is russet green. This is revealed in comic 318, shortly before Flower insults him for this.
After gaining the ability to use magic Cyril became actually useful in combat.
This spell was used in comic 419 and is most likely a reference to the Japanese game Ni No Kuni: Wrath of the White Witch.
Cyril summons a giant bunny to crush his opponent. This was only seen used on Xane (comic #400).
Cyril summons a orb of light to vaporize undead entities. He used this spell accidentally while reading a book.
