Olasird'arc Haylilyal

The Frost Dragon Lord of the Azellisia Mountains, who makes his base in the castle of "Feo Berkana," the former royal capital of the Dwarven Kingdom.

His power, capable of wielding three types of third-tier magic, is formidable in this world. During his numerous conflicts over territory with Munuinia, who later became his queen, the western Dwarven city of "Feo Teiwaz" was destroyed and turned into ruins. His growth as a dragon in the post-transference world has reached the highest peak. Unlike other typical dragons, he allows his adult children to live in his stronghold and believes in uniting his clan to deal with external threats. His ranking among kings is 9th out of 12 (prioritizing himself).

After receiving a petition from Pe Riyuro, he sent Hejinmal to deal with the intruders, but Hejinmal surrendered.

Due to his arrogance, a trait inherent to dragons, he ultimately provoked Ainz, who had come before him, and was instantly killed by a ninth-tier spell. His body was sent to the fifth floor of Nazarick (Glacier) for preservation to be used in experiments.
