Blade of the Warden
From RPGWiki
A large polearm, similar in design to a naginata or svärdstav. It was held by Jenrakasandi through his vigil beneath the Netherine Titan, and was the key to the Titan's prison as well as a powerful weapon in its own right.
In the hands of a capable wielder it has some power over flame, but its true capabilities may be known only by the salamanders.
