Alec Lightwood

Because the books are vague about the placement of Alec's runes (or they are listed in different locations from book to book) I use the placement that's been seen in Shadowhunters as a guide for where Alec's runes are. The main differences between Book Alec and Shadowhunters Alec are the runes that are listed as not shown in Shadowhunters (see below) and Voyance on the back of his right hand.  The tracking rune used on Shadowhunters has never been described or used in the books.  A guide to what each rune looks like and its deception can be found here.  Runes with strikeout text are ones that the book version of Alec does not have.

In the books, Alec has two runes that have not been shown in Shadowhunters as of 3/4/2017.

Fearless - On his left arm. This rune makes a Shadowhunter unafraid of his or her worst fears. When Alec used it, he attempted to come out to his parents, but was stopped by Magnus before he could tell them about being gay and he was dating Magnus. This rune was created by Clary in City of Ashes.

Alliance - On his hand. This rune is a temporary partnered in fighting rune. It allows a Shadowhunter to bond temporarily with a Downworlder. The beings share each other's abilities. The Shadowhunter will share the strengths of the Downworlder that he or she is bound to. The Downworlder will share the Nephilim's fighting abilities. Alec's partner was Magnus Bane. I headcanon that the placement was on his left hand. This rune was created by Clary in City of Glass.

In the books, the Iratze isn't shown as a permanent rune. It is normally partially drawn before battle, and then completed/activated when the Shadowhunter is injured.  If the first Iratze doesn't heal the wound, others are drawn.  Some wounds cannot be healed with this rune.  Alec has scars from one of these wounds on his chest from being clawed by a demon when saving Jace in City of Bones.
