Verðandi is slightly shorter than her older sister Urðr, but is still taller than a fairy. Her hair is also of the same golden colour as her elder sister's, but is a little shorter, and her dress is deep blue in colour. According to Kirito, Verðandi's face could be described as «elegance».
Verðandi was created by the Cardinal System’s Automated Quest Generation function, which based the character on a myth from Norse mythology. Unlike most quest NPCs, Verðandi's core programming is connected to the language engine module, therefore, instead of having a fixed response routine, she has a certain level of Artificial Intelligence and is thus capable of much more flexibility in her dialogue routines as well as sounding far more realistic than a regular NPC.
