The teenagers see her looking at them, and appear shocked that she can see them. Clary Fray cannot understand what she just saw. Before she can make any sense of this incident, her mother disappears, and Clary herself is almost killed by a bizarre creature. One of the mysterious kids she saw at the club helps her, and she discovers that he and his friends are Shadowhunters, a group of warriors dedicated to protecting the earth from demons. The boy whom they killed at the club was a demon. The young shadowhunter who helped Clary introduces himself as Jace, and she also meets the other two teenagers, Isabelle and Alec. All of them are puzzled at how Clary can see them, for mundanes, as normal humans are known in the Shadowhunter world, cannot see them.
