Titu

Titu is a non-player character (NPC) in the Natlan region of Genshin Impact. He first appears in the world quest "Shadows of the Mountains." Titu belongs to the "Children of Echoes" organization, which seems to be related to maintaining a certain seal. During the quest, the Traveler must assist Titu in resolving the issue of "Shadow Pins" appearing in the Sulfurous Veins and reinforce the seal on the Abyss. Titu's personality is somewhat mysterious, and he seems to have knowledge of ancient lore. His questline not only advances the plot in Natlan but also reveals some deeper secrets about the Abyss and the continent of Teyvat.
