- "It's a portable planetarium."
"It's a compass."
"Compasses generally find things."
"Indeed. Have either of you gentlemen heard of the Spear of Destiny?"
- —Malcolm Merlyn, Eobard Thawne, and Damien Darhk discussing the amulet[src]
The Askaran Amulet, also called the Longinus Medallion, was an ancient Judeo-Christian artifact composed of two pieces. Gideon's specs on the artifact identified it as originating from the first century AD, and indicated it had some sort of occult power. When Eobard Thawne put the two components of the amulet together, he revealed it to be a compass, which could locate the Spear of Destiny.
In 1942, time-traveler Eobard Thawne/The Reverse-Flash made an agreement with Baron Krieger to trade the amulet in exchange for a drug to create Nazi super soldiers. The Legends and the Justice Society of America infiltrated Folies-Bergére, a Parisian nightclub, discerning that Krieger had the amulet. They intercepted Krieger and the Nazis at the Fontainebleau Forest and retrieved the amulet. Later at the JSA headquarters, Eobard arrived, killing Rex Tyler/Hourman and taking the amulet.
In 1927, Malcolm Merlyn, some of Al Capone's men, and Eobard invaded the Waverider and took the second part of the amulet back. Eobard later combined both pieces to reveal a miniature planetarium, saying that it was the key to locating the Spear of Destiny.
The amulet was finally destroyed by Rip, while he was under mind alteration by the Legion of Doom, during his brief escape from the brig of Waverider. After having been freed and cured by Sara, Jax and Gideon, Rip rejoined the Legends and revealed where and when Henry Heywood/Commander Steel and the last fragment of the Spear of Destiny were located.
