As Jinwoo continues his training, he completes a daily quest one day by doing more than the quest requires, and a key that leads to a certain item appears in front of him.
Is this for the gate that 
Cerberus was protecting?
هل هو للبوابة التي كان ذلك الكربروس يحميها؟
Ist der etwa für das Tor,
das Kerberos bewacht hat?
¿Esta es de la puerta
que custodiaba Cerbero?
¿Esta es de la puerta
que custodiaba Cerbero?
Elle ouvre la porte
que gardait Cerbère ?
Sarà per il cancello protetto da Cerbero?
É a chave da porta que
o Cerberus guardava?
Видимо, он к вратам,
которые охранял Цербер?
