The complete set of all rider blades mentioned in the Inheritance Trilogy by Christopher Paolini
Arvindr: Only the name was briefly mentioned in Brisingr, although it is known to have been wielded by an elf rider. Its colour is also just a guess, but was the favourite choice from those on the Inheritance forums.
Naegling: The blade of Oromis, the Mourning Sage.
Brisingr: The sword forged (indirectly) and wielded by Eragon- with a tendancy to catch on fire.
Vrangr: The bone-white weapon of Galbatorix, stolen and renamed after the death it’s original holder Vrael.
Zar’roc: The original sword of Morzan, which has passed through several hands, ultimately resting with Murtagh.
Tamerlein: A sword once kept under the guard of Lord Fiolr, that now, after adjustments, is held by Arya.
Undbitr: Another sword that did not actually make an appearance, and was just mentioned. It was the sword forged for Brom, whose dragon was blue, although a different shade from Saphira.
A few extra notes- the designs for Brisingr and Zar’roc are inspired by the official inheritance artwork, all the others are my original designs.
Also in terms of the order, the two swords that were not actually seen are placed on the outer edge, with the others arranged as I thought looked best.
