The necroswords were obsidian swords used by Hela during Asgard's era of expansion throughout the Nine Realms. However, Odin, Hela's father and king of Asgard, ultimately imprisoned his daughter in Hel to quash her expasionary ambitions, which he had begun to see as a threat to order within the Realms. Hela managed one escape attempt during her imprisonment, forcing Odin to send the Valkyries to subdue her. Hela proved no match for the elite warrior force, however, summoning a barrage of necroswords to kill all but one of her assailants.
Thousands of years later, in 2017, Hela would eventually be released from Hel after her father's death. After Odin passed away in Norway, Hela appeared, coming out of a portal. There, she was confronted by her two brothers, Thor and Loki, who insisted on making a peace offering. However, Hela later attacked her brothers and eventually made it to Asgard via Bifrost Bridge. At Asgard, she used her necroswords to massacre and kill most of the Einherjar.
During the final battle between Hela and the Revengers, Hela again used her necroswords to attack her enemies. However, as Surtur, who was reborn with the power of the Eternal Flame, fulfilled the prophecy of Ragnarök, destroying Hela, Asgard, and the rest of its inhabitants.

To be added
- The necroswords are based an amalgamation of two different weapons from the comics: the Nightsword Hela's cursed sword that she was able to summon at any time; and the All-Black, the first symbiote who manifested his form into a powerful sword with dark properties, created by Knull and previously wielded by Gorr the God Butcher, both of whom used it to slay gods across the cosmos.
