Altavaska

A weapon that can kill something that cannot die. The Twilight Gryphons found out about this weapon from a woman who came to them from 100 years in the future. She found out about it and about the party from Goldspire in the future. Apparently in her timeline the party failed to stop the Ritual of Evernight so she was sent back to help them win with this information. To build this they need: They are told that the weapon will assemble itself when its name is spoken. They are warned to only use it when they must as it takes a toll on the user.
 * Core
 * Crystal capable of holding great energy (Obtained!)
 * As spoils from a game with Rindel, Ryker finds out that one of these resides in the Arcana Mysterium (Great Library of Faerun) in Bezantur . The last he saw it, it was in the research laboratory of Perria Shadowbane.
 * Fragment of Prime-bound Divine - infuse into crystal (Obtained and Infused!)
 * Goldspire of the present day tells Albrek, Amari, and Ryker that the only prime bound deity that he knows of is Zhenka - god of deaths, debts, and misfortune. Last he heard, this god was in the North Country near the Icerim Mountains. In exchange for this information, Ryker owes him Zhanka's hammer by Flamerule 20 the next year.
 * Willing mortal - infuse into crystal
 * Vessel
 * Forged of Jaskite Steel
 * Found in the Plane of Earth. The party has a key that will take them there that they plan to use.
 * Albrek knows of an incredible blacksmith in Ironspur that may be able to forge it once we get the steel together.
 * Halbran also tells the party of a legendary blacksmith in Icewindale that supposed continued to forge even through death
 * Soak in fey-blessed water
 * Tempered full day under Dark Moonlight
 * Dark Moon is what is found in Shadowfell. Iram gave Amari a boon that she can use to get to and from another plane (One time, round trip). They plan to use this to get this part.
 * Runes carved on Core and Vessel
 * "Runes carved by the one made to complete this task before their end"

The Twilight Gryphons are also given an unmarked 11" x 11" metallic cube. It's not magical and has no seams. Amari is able to connect to it mentally and it speaks to her.
