Alliance is a rune that 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. Existing long before the Nephilim, 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 considerately 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, which they ultimately won.[1]
The Mark itself is actually a matching pair of runes, each one meant to be drawn on the other by the partners intending to be bound.
