Skuld

スクルド

Skuld is one of the NPCs part of «The Holy Sword of the Ice Palace» quest. [Spoiler] Skuld 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, Skuld'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.
