Kurudan

Kurudan (쿠르단, Kooreudahn; or Kurdan or "Kurudan") is a Ranker and member of  Wolhaiksong. He travelled with Yuri and her group, whose objective was to navigate the more dangerous parts of the Middle Area in order to infiltrate the Second Floor so she could retrieve the Black March. However, Kurudan thought they were going to start a war with Evankhell and seemed disappointed when Evan Edrok scolded him for thinking so.

Tower of God: Part 1
Kurudan accompanies Yuri group to the second floor seeking Black March, though in doing so must venture along a road where there a herd of steel eels is present, implying the road has a high density of Shinsoo. Kurudan claims to Yuri that if there is someone capable of moving freely around it, he would happily give them his emblem of the Winged Tree. Yuri replies that when they arrive at their destination he would have to be prepared to give the emblem of the Winged Tree (this symbol was given to recognize the power of a Wolhaiksong member; it is unknown what state or rank Kurudan has within the organization, though it can be assumed to be relatively high up).

When Kurudan arrived on the second floor, he wound up facing Ren at Yuri's command. As a Princess, Yuri was not allowed to attack anyone who worked for the Zahard Empire unless authorized by the King. Hence, she needed someone to act on her behalf, to avoid any political complications. As a result Kurudan adopted her place as an opponent, and crushed Ren enough to incapacitate him.

However, after Kurudan defeated Ren for Yuri, she instead gave his Wing Tree feather to Leesoo, before telling him to give the feather to Baam.
