Sybrian was a shadow, or Dark Scout, that was controlling Trellis before being defeated by Emily.
When Trellis was studying with his uncle, his father, The Elf King, came into the room, telling him to not study with his uncle. He soon got his guards and took away his uncle, likely to imprison or execute him. Then he introduces Sybrian, telling Trellis that he will be his new partner. Trellis refuses, then his father smacks him and makes him bleed with his sharp nails, causing him to get the scar on his eye. After that, Sybrian is his partner from now on.
Trellis later used Sybrian to force Emily into submission. However, when she used the stone to free herself from Sybrian's grasp, the creature splattered and dissolved.
Escape From Lucien
Sybrian is also mentioned in "Escape From Lucien" , where his species is revealed to be called Dark scouts, sometimes simply called Shadows. Max Griffin explains that it is a parasite-like creature and that "once it enters the host's nervous system, the creature takes over command of the mind and body. When it gains full control, it begins to wreak havoc on others."
- He is supposedly the second oldest character, second to Ikol.
