The Yawë was an elven symbol that indicated a bond of trust. According to Oromis, it was a glyph in Liduen Kvaedhí, or the Poetic Script, which is the elves' written form of the Ancient Language. Arya had it as an indigo tattoo on her shoulder, and Brom had a Sapphire ring, Aren, which was later bestowed upon Eragon. Being given a ring with this symbol indicated that you were an Elf-friend. The yawe is also the name of the written form of the ancient language.
