Nesta's Dagger is a magic dagger created by Nesta Archeron.
Description[]
The dagger is simple and made of steel, the blade seems to gleam like an icicle in the sun .[1]
History[]
Cassian had taken Nesta to a blacksmith in Velaris so she could learn how weapons were made, the hard work that came with creating them, and thus appreciate them before actually wielding them. Nesta created the magic dagger unknowingly while practicing hammering at the metal for a while infusing it with her power of silver flames while she made it.
Later on Rhysand gave the dagger to Eris as a Solstice gift, and to solidify their alliance.[1]
