Was doing the zodiac weapon and one task in the book is the kill diabolos in The Lost City of Amdapor. Then I realise I never been in that dongeon. From my search I need to talk with E Sumi Yan to unlock the quest that unlock the dongeon after finishing the quest Ultima Weapon.

I did finish this quest 2 weeks ago, but E Sumi Yan doesnt have any quest for me. Am I missing something ?
