"Bind To" rune.

The Alliance rune allows Shadowhunters and Downworlders to safely share each other's abilities, giving the Nephilim access to the strength, speed, and magical abilities of their Downworlder partners, and giving the Downworlders access to the warrior skills of their Nephilim allies.


The Mark itself is actually a matching pair of runes, each one meant to be drawn on each other by the partners intending to be bound.[1] The runes are interchangeable between the Shadowhunter and Downworlder, and like most runes, it fades after use.[2]


Existing long before the Nephilim, the Alliance rune was not found in the Gray Book—or the Book of the Covenant bestowed upon the Nephilim.

In 2007, Clary Fray received an image of the rune through visions sent to her by Ithuriel, which she then later relayed to the other Shadowhunters and Downworlders. This rune helped them considerably in the battle against Valentine Morgenstern and his army of demons and helped the Nephilim and Downworlders turn the tide in their favor just before the Mortal War.[1]

In 2010, Alec Lightwood and Magnus Bane used the rune again in Diyu. The rune presumably allowed Alec to survive being stabbed by the Svefnthorn, which would normally have killed anyone who is not a warlock. The rune and the Svefnthorn's magic gave him the power to remove the weapon's power from Magnus, effectively freeing him from its fatal effects.[3]


These are all the known alliances made with the rune:
