Urd

Urd is one of the rulers of the Beast-type Evil Gods in ALfheim Online and the NPC that gives «The Holy Sword of the Ice Palace» quest, the real quest for acquiring the «Holy Sword Excaliber». Urd 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, Urd'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.
