Taglonen was an Abronian, one of the last surviving members of the species who evacuated their doomed homeworld on a ship built from their planet's moon.
In the 3180s, Taglonen awoke from cryostasis when grave robbers attacked the Abronian ship, and managed to send a telepathic distress call that drew the attention of J'Vini, a sister of the Qowat Milat. Taglonen succumbed to his wounds as J'Vini dispatched the last of the grave robbers. To honor him, J'Vini covered his body with her cloak and took on his cause as her own: to protect the Abronians and ensure that they would wake to settle their new home. (DIS: "Choose to Live")
