Kloinjer was an artifact acquired by Tira Miron during the Year of Blood and Fire. It contained the soul of a couatl by the same name, and seemed to be tailor made to counter Bel Shalor, the Shadow in the Flame and its minions. Kloinjer had a silvered blade and a large Khyber dragonshard embedded into the pommel, allowing the blade to bind fiends that fell to it.
Tira Miron was awarded the greatsword Kloinjer by the Ghaash’kala and wielded it in her final battle against the Overlord Bel Shalor, the Shadow in the Flame. Bel Shalor was immune to the radiant powers that Tira and the others wielded, but Kloinjer temporarily stripped it of this immunity, allowing them to harm it.
