Darach

Within the mythology of MTV's Teen Wolf, Darach is what characters call the unknown killer responsible for several ritualistic murders during the first episodes of Season 3.

The Darach pretended to be Jennifer Blake, an English teacher at Beacon Hills High School.

Her real name is Julia Baccari and she was once the Druid Emissary to Kali's pack.

History
According to Dr. Deaton, Darach means "Dark Oak". This information is presented in opposition to the word Druid which Deaton says means "Wise Oak".

Deaton claims the word would be applied to one who "went down the wrong path". (read more...)

When Deucalion had the various Alpha's kill their packs, he also had them kill their emissaries. Kali loved Julia, and while she brutally slashed her and left her for dead, she could not bring herself to deliver the killing blow.

Julia survived by making it to a nearby Druid Nemeton (sacred space) which had been given power by the recent death of a virgin (Paige in Visionary). This power reserve allowed her to survive until help arrived.

All the sacrifices she performed in Season 3 were an attempt to gather enough power to defeat the Alpha Pack during the upcoming lunar eclipse.

Season 3
Stiles, Lydia, Allison and Scott are in her English class. On the first day of school Ms. Blake texts a quote to all her students with phones in class. She explains that it is the closing line to the first book they will be reading in her class (“Heart of Darkness” by Joseph Conrad) and that it will also be the last text any of them receive in her class. She instructs them to turn off their phones. A panicked flock of birds crash through the windows of her classroom. (read more...)

Modus Operandi
In each attack seen on screen, victims suffered visual or auditory hallucinations before they were taken.

In the first six cases, the killer employs a Threefold Death ritual, using three different types of fatal blows on each victim -


 * Blow to the Head
 * Sliced Throat
 * Strangulation by Garrote

After the first six, the Darach changed to a crucifixion-like hanging method where the individual is suspended by the hands.

The victims still suffocate but the manner of their death takes longer and they suffer more.

The victims, in groups of three, seem to be chosen due to some common status.


 * Virgins
 * Warriors
 * Healers
 * Philosophers
 * Guardians
