Featurette: ‘Shadowhunters’ Glossary, Volume 2
SHADOWHUNTERS - “The Mortal Cup” - One young woman realizes how dark the city can really be when she learns the truth about her past in the series premiere of "Shadowhunters" on Tuesday, January 12th at 9:00 - 10:00 PM ET/PT. ABC Family is becoming Freeform in January 2016. Based on the bestselling young adult fantasy book series The Mortal Instruments by Cassandra Clare, "Shadowhunters" follows Clary Fray, who finds out on her birthday that she is not who she thinks she is but rather comes from a long line of Shadowhunters - human-angel hybrids who hunt down demons. Now thrown into the world of demon hunting after her mother is kidnapped, Clary must rely on the mysterious Jace and his fellow Shadowhunters Isabelle and Alec to navigate this new dark world. With her best friend Simon in tow, Clary must now live among faeries, warlocks, vampires and werewolves to find answers that could help her find her mother. Nothing is as it seems, including her close family friend Luke who knows more than he is letting on, as well as the enigmatic warlock Magnus Bane who could hold the key to unlocking Clary's past.

While fans of Cassandra Clare’s Shadowhunter Chronicles are already well-versed in all of the terminology associated with her world, there are new fans joining the fandom every day, so Freeform thought they’d help these new fans brush up on some of the most important words to know in the Shadow World.
Strap in for “A Mundane’s Guide to Shadowhunters, Volume 2,” where the cast and Cassie discuss the terms “Parabatai,” “Seraph Blade,” “Downworlder,” and “Ravener Demon.”
Shadowhunters premieres Tuesday, Jan. 12 at 9/8c on Freeform.

Parabatai are more than just “close friends”!! They are practically a part of each other that they can’t live without. They are the heart and soul of each other! Yeah, just needed to say that to all y’all mundanes out there, so you can understand the relationship between Jace & Alec, and WILL AND JEM
I think the ravener demon on the film was more accurate and scarier than the one on the show. It’s interesting though, to see how the two different medias interpreted the appearance of the demons from the books.
