Iron Sisters

**The Iron Sisters** are a communal organization of female Shadowhunters that forge weapons for their kind. The Iron Sisters are considered the female counterparts of the Silent Brothers, albeit more secluded. They reside in the Adamant Citadel, where they live in almost total solitude and speak only, and occasionally, to female Shadowhunters.

## Description

The Iron Sisters are a monastic order of warriors. They take upon themselves arcane runes that grant them access to the hidden, deeper sections of the Gray Book. For them, their Marks give them the ability to work the angelic stone adamas, making them the keepers and the only ones able to shape, craft, and handle the metal, particularly in its pure and unprocessed state, into arms, armor, and tools that the Nephilim need. These Marks of transformation also overwhelm and dissolve the parabatai Marks of binding and other ordinary Marks.

The Iron Sisters are even more private and removed from Nephilim society than the Silent Brothers. They do not like to be bothered and prefer to work in isolation, particularly not wanting interference from male Shadowhunters. The Iron Sisters rarely leave or venture outside of their usual domain, the Citadel.

Their motto is "Ignis aurum probat", which translates to "Fire tests gold." It not only refers to their role as forgers for their kind, but also describes the Iron Sisters themselves: hard, unyielding, and strong. It also refers to how adversity tests one's strength of character.

The Sisters call upon the power of the angels to imbue their energy into the blades they make, during which they hear the angels whisper. Their blood is also apparently purified.

## Tasks

The Iron Sisters are responsible for creating, forging, designing, and repairing the weapons, armor, and tools, among others, that aid the Nephilim in their quest against demons. With their forges that get fire from the heart of their Citadel volcano, using adamas along with several other materials, they craft seraph blades, steles, special leather for Nephilim battle gear, and much more.

The Iron Sisters refresh the power of exhausted or depleted seraph blades. They extract witchlight stones from the adamas rock and work them to give it its glowing function when touched by Shadowhunters. The Iron Sisters are also the keepers of the angelic exotic weapon aegis, rare daggers seethed and tempered in angel blood, needed in the severance of parabatai bonds, which they unwillingly lend out to those who are in need of it.

Along with the Silent Brothers, Iron Sisters are also traditionally responsible for placing the protective spells on newborn Shadowhunters, each represented by one of theirs.

Iron Sisters can break runes like the Wedded Union Rune.

## Physical Description

Iron Sisters all wear pale, long white gowns, bound tightly at the wrists and waist by demon-wire, to protect their clothes from the holy fires in which their materials are worked. The gowns blend in with the mist that encroaches the Adamant Citadel, so when they come to speak with someone, they seem to appear out of nowhere.

## History

The founder of the Sisterhood was Abigail Shadowhunter, Jonathan's elder sister. When she grew older and found that she could no longer wage war against demonkind as she had in her youth, she turned to the esoteric knowledge of the Gray Book and the beating angelic heart of adamas beneath Idris to become the first Iron Sister. Along with six other Nephilim, she constructed the first adamas forge, and the earliest incarnation of the Adamant Citadel upon its volcanic plain.

## Trivia

Much like the Silent Brothers, the Iron Sisters also age slower than normal humans, and thus have a longer lifespan.
