• Downworlders cannot bare the marks of the Shadowhunters. The only rune they can bare is the Alliance rune created by Clary Fray, that allows Downworlders and Nephilim to share abilities.

Runes

Runes:

• Runes or Marks are angelic symbols that the Nephilim burn into their skin, using steles, to give them various "supernatural" abilities. 

Runes are the Nephilim or Shadowhunters most used tool to help fight demons. Runes are a complex array of symbols and language given to Shadowhunters by the angel Raziel, that give Nephilim a power mundanes can not bare.

• They were given to the first generation of Shadowhunters by Angel Raziel so that they could fight off demons. Every rune accessed by a Shadowhunter is written in the Gray Book.

Most runes are temporary and fade off, leaving a thin white scar in its place. Other runes are permanent and stay on forever. 

• If a rune written in the Gray Book is burned into a mundane, it can drive them insane and turn them into Forsaken.

The closer the rune is to the heart the more effective the rune's power or ability is. Most runes can be placed on other objects like rocks or bricks.

In the first book City of Bones Jocelyn is taken by Valentine and his demons, but before he could get through the door Jocelyn takes a potion that puts her under a coma so that she doesn't tell him about the Mortal Cup's whereabouts. Before Jocelyn found out what Valentine was really up to, she was his wife and their love was endless.

In order to pull Clary's mother out of her coma, Clary must travel to the City of Glass in search of a powerful warlock named Ragnor Fell. Many of the Shadowhunters are going to Idris to meet with the Clave and discuss matters involving Valentine, but with Jace determined for her not to go, he gave her the wrong time. When the portal was finally opened and Clary was at home packing, the group of Shadowhunters were attacked. To save themselves from being killed and to keep Simon from dying, the portal was their only option. When Clary finally arrived and found out they had left without her, she used her ability to create new runes and opened another portal to Idris, which was not permitted. Clary went through with Luke on her heels, and they both landed in Lake Lyn. To keep Clary from dying of Lake Lyn's poisonous waters, Luke had to break into Idris to seek help from his sister. Before Clary wakes up, Luke leaves without a description of where he was leaving to. Clary sneaks out to find Jace and the Lightwoods, which is an unpleasant surprise for Jace. There she meets Sebastian Verlac, who walks her home and helps her to find Ragnor Fell, who is instead Magnus Bane. Sebastian is frozen and Clary is told to find the Book of the White in the Wayland Manor, which holds the recipe of a potion that will pull Clary's mom out of her coma. Valentine, on the otherhand, decides to wage a war against the Clave giving them the option to either side with Downworlders and fight, or side with Valentine. When the Clave decide to side with Luke and the Downworlders, Valentine flees to Lake Lyn to summon Angel Raziel and create a more powerful version of Shadowhunters with demon blood in them. Raziel denies his request and kills Valentine, granting Clary's wish to bring Jace back to life.

City of Ashes

Just recently Clary Fray found out that there were two worlds. The world she had lived in for 15 years and the world of the Shadowhunters. Although Clary wants her old life back and more than anything to spend time with a growing flame, Simon, the Shadowhunter world doesn't seem reluctant to let her go. With her mom in a potion induced coma and Clary's new ability to see things that normal mundanes shouldn't be able to see, like Downworlders, the option of leaving the Shadowhunter world is all but dissipated. In her search to pull her mother out of her trance, Clary just might have to throw away everything she use to know and track down her only chance of getting her mother out, the evil Valentine, who also happens to be Clary's father. But to defeat Valentine, Clary must seek the help of her new found brother, Jace, if he is willing to side with Clary and go against the father he thought was dead.

City of Bones

When 15-year old Clary Fray heads out to the Pandemonium Club with her friend Simon, her world is turned upside down. She witnesses a murder committed by three teenagers on a boy that wasn't even an actual boy. The weirdest part yet is that she seems to be the only one witnessing it, even though the club is full of people. Traumatized by what she had just seen, Clary decides to forget it even happened, but it is hard to forget when one of the teenagers, Jace Wayland, continues to make pop-up appearances. When Clary finally confronts Jace, her mother gets attacked and abducted, and she is forced to fight    a demon. This causes a ripple of events that lead her to finding out if the life she had been living for 15 years was really her life at all.
