Update on where we are with the Narsil storyline, based on Session 6-11 (Finale of the Beren and Lúthien Season):
Season 4
1) Aegnor's sword breaks during the Dagor Aglareb.
2) Maedhros commissions Telchar to make a new sword for Aegnor.
3) Telchar forges Narsil.
4) Maedhros gifts Narsil to Aegnor
Season 5
5) Aegnor uses Narsil in the Dagor Bragollach.
6) Aegnor dies in battle against balrogs.
7) Narsil is recovered and delivered to Finrod, Aegnor's brother.
8) Finrod gives Narsil to Andreth, Aegnor's love.
Season 6
9) Andreth lives in the Forest of Brethil, keeping Narsil.
10) Andreth passes Narsil on to Emeldir.
11) Emeldir takes Narsil and the remnant of the House of Bëor to Dor-lómin.
Our goal is for Narsil to become 'the sword of the Faithful'...but our most immediate challenge is to keep it out of the Hill of the Slain after the Nirnaeth Arnoediad in Season 7.
Prior to this, the most extensive discussion of the Narsil storyline was in Session 5-29 (the Culture of the Edain). This was where we had discussed Túrin passing over Narsil in favor of Gurthang while living in Brethil, though that is (sadly) unlikely to fit into our story moving forward.
1) Season 4 - Narsil is forged by Telchar. Narsil is commissioned by Maedhros as a gift for Aegnor, whose sword broke in the Dagor Aglareb.
2) Season 5 - After Aegnor's death in the Dagor Braggolach, Finrod will gift this sword to Andreth, in memory of his brother.
3) Andreth will join the refugees from Dorthonion in Brethil. The sword will become a treasured heirloom among the Haladin.
4) Narsil will make its way to the Havens by the end of the First Age.
5) During the Third Kinslaying, Maedhros will recognize Narsil and pick it up as spoils from the battle. His brother Maglor will pick up a young Elrond and Elros.
6) Elrond will be gifted Narsil by Maedhros at some time before the end of the War of Wrath. Narsil will be Elrond's sword while he serves as Gil-galad's herald.
7) At some point during the Second Age, Elrond will gift Narsil to a Numenorean who aids the Elves in their battles in Middle-earth against Sauron. This individual will either be a Lord of Andúnië, or their descendants will be. Narsil becomes the sword of the Faithful.
8) Amandil will gift Narsil to Elendil prior to the drowning of Númenor.
...and we know the rest from there.
