Hidden Exploration Objectives (unofficial name), or HEO for short, are many things around the world of Teyvat that are not normal Exploration, but are not officially recognized as Quests or marked in any way. They tend to be associated with Wonders of the World achievements.
They can be divided into the types "Quest-Like" and "Unordered."
Quest-Like[]
These follow the structure of a normal quest, with a defined set of steps, and explicitly present some lore.
