One of the Noldor, who has seen the Light of the Two Trees, this high elf is aged and old. Thus, it makes sense that she would carry many, many names.
Alasiel.
Quenya: Day Maiden.
"I am Alasiel. A pleasure to meet you, hir!"
The Quenya mother name given to her when she was born in Tirion in the Years of the Trees. Alasiel bore the name until Quenya was banned in Beleriand, then changed it to her Sindarin version.
