Since we have mentioned Elves and Night Elves, it must be observed how they differ in appearance and personality.
Elves are very fair, with long ears, emanating detachedness and preferring to avoid contact with people. They long for nature and tend to go with the flow.
On the other hand, Night Elves are very dark, with shorter ears, known for their craftiness and worship of destruction. All their habits are formed around this principle.
Thus, it is not difficult to see that the hatred between Night Elves and Elves cannot even be extinguished by the melting of Mount Tamerlarya.
Being one of the prince's heirs, Delsa is no exception. Compared to ordinary Night Elves, he knows many more secrets, which deepen his hatred towards Elves.
If initially he felt helpless upon arriving on the Aegean Continent, he now has a goal, to find the Elves, to take revenge on the Elves. As for the revenge methods, Delsa dislikes bloodshed and doesn't mind sacrificing himself.
