The Asterkinj is a living creature called a Kinj that relies on the survival of a host to stay alive. This blue-tinted kinj gives its host the ability to open portals to the Plane of Ashes. However, it can only open one portal at a time and the portal won't stay open for long. It is one of seven original Kinjs.
The One that the prophecy foretells can use the Asterkinj to release the Lu-Qiri and Blackbloods from the plane of ashes. Because of this, many believe that they should be the true wielder of the Asterkinj.
In "Two Heads Are Better Than None", Talon has a nightmare about her village massacre and the Plane of Ashes. Against The Smith advice she reads the parchment out loud. This actives the Asterkinj to open a portal bringing forth Baphnoro to the realm.
In "We Only Kill to Survive", Talon has received a Lu-Qiri name from Ilyin. Talon then uses the Asterkinj to summon Enkundi who is then followed by his master. Later on, Rebb attempts to carve the Asterkinj out of Talon's forehead. However, the creature moved to Talon's hand to avoid being removed forcefully. When Talon awakened, the creature returned to her forehead.
In "Not In My Kingdom", Talon meets with Rebb to transfer the Asterkinj to Rebb. Talon places her hand on Rebb's forehead and the Asterkinj travels from Talon's forehead to her fingertips. The transference is interrupted and Talon keeps the Asterkinj.
In "The Blade of The Three", Queen Rosmund forces Talon to send Vikka back to the Plane of Ashes. At night, Zed summons Vikka, who appears in the fog. Talon then opens the portal to the Plane of Ashes. Zed then tells Vikka to go through the portal. Vikka is reluctant at first, but after Zed yells and commands him a second time he goes through.
In "Where You Go, People Die", the Asterkinj opens a portal to the Plane of Ashes and Talon is sucked through. When she awakens, she experiences physical pain stemming from the Asterkinj. Another portal appears and she jumps through it, arriving back on her plane once more.
In "The Only Way", Talon speaks about learning to control her Kinj. At first, it sensed when she was in danger and protected her. But now, she just has to concentrate on what she wants and a portal opens. Later, Zed attempts to use his Kinj to manipulate her mind but the Asterkinj refuses to allow Talon to be manipulated. She can feel it protecting her from the Kinj's interference. After defeating Zed, she states that she should kill him but spares his life instead. She then uses the Asterkinj forcing Zed back into the Plane of Ashes.
In "This Is Our Outpost", realizing that the time is right for the prophecy to be enacted, Talon once again summons Vikka and Zed. Zed then calls out more Lu-Qiri and Blackbloods into the realm to fight and win against the Prime Order.
In "For the Sins Of Your Ancestors", Talon is forced to use the Asterkinj in order to save her friends. She then opens a portal to the Plane of Ashes allowing Zed to call forth Ketma, who is then followed by his master Yavalla.
In "The Hardest Part of Being Queen", Falista reaches out to Talon in an attempt to learn more about the Kultorkinj inside her. Talon explains that she can't help her learn to control the kinj as that's something she needs to figure out alone. She does empathize with Falista's inability to control the kinj, as the Asterkinj acted on its own before in an attempt to protect her. She warns Falista to control her emotions. Talon than uses the kinj once more to open the portal so she, Wren, and Zed can travel to the Plane of Ashes.
The Asterkinj can’t survive outside a host's body. The creature wants to survive like any other living thing, so if the host dies the Asterkinj can leave the host and find a new one.
Alternatively, the Asterkinj is passed down from parent to child. The current owner of the Asterkinj must place their fingers on the next holder's temple and the Asterkinj will flow to the new owner.
When Rebb tried to remove the Asterkinj from Talon by cutting it out, the creature moved inside Talon's body until Rebb stopped.
