The God of Wisdom's enemy is wisdom itself, and the oasis of knowledge is a mirage in the desert of ignorance. In the city of scholars there is a push for folly, yet the God of Wisdom makes no argument against it.
Sumeru's landscape features both deserts and forests. In the Teyvat Chapter Storyline Preview, Dainsleif likens it to a desert, and Liben mentions that "Sumeru is all rainforest and desert".
500 years ago, during the cataclysm, the previous Dendro Archon was slain and the current God of Wisdom took their place. Under the aegis of the God of Wisdom, the sages of Sumeru drive themselves into hysterics and abandon all that is worldly in their pursuit of esoteric wisdom.
Lisa went to study magic at the Sumeru Akademiya, where she was considered the best student they had seen in 200 years. Despite the prestige she enjoyed there, she ultimately returned to Mondstadt after growing disillusioned with the "raving-mad scholars" and the cost of "uninhibited erudition" she witnessed in Sumeru.
The Eremite are a faction of mercenaries from Sumeru who travel throughout Teyvat. They see themselves as people who are not "afraid of dying so that they might truly live." Nazafarin, a scholar from Sumeru, claims that some of its members wield "bizarre yet formidable powers," and finds the subject of the Eremite unpleasant enough to swiftly drop the subject after briefly explaining them to the Traveler.
Sumeru's Statue of the Seven depicts a female figure who appears to be a child. She is shown to be wearing a similar cloak and draping clothing similar to the other known Archon statues. Her small frame is also shown sitting on a huge leaf, an attribute owing to her mantle as the Dendro Archon.
Dharma Forest
Dharma Forest is a subregion located in Sumeru. It is the rainforest subregion for this territory.
A fragrant wind comes from the west of the rainforest, carrying stories that have never been heard.
The nation of wisdom sleeps soundly under the green veil, and all creatures sing under the cleansing rainwater. Amidst the luxuriant branches and leaves, the new chapter of the journey unfolds.
Great Red Sand
The vast desert in the western part of Sumeru is known as the Great Red Sand. In this world of sand, ancient ruins and mysterious treasures await you...
—Sumeru Adventure Journal: Trail of the Sea of Sand
Crossing sand and searing wind, traversing thicket and forest, you reach a ruined city that was once part of a kingdom of gilded desert.
Though the mirage has faded, the ancient dreams and secrets yet slumber under the shifting sands.
Gandharva Ville
The city above the forest.
"The city of wisdom is ours, as is the forest of ignorance. Atop the tree lies the remnants of the kingdom of lost dreams."
Pardis Dhyai
The garden of deep thought.
Countless flowers lie within the garden, each more lovely than the most beautiful crystalfly. This is the paradise of people of goodwill.
Caravan Ribat
The frontier beneath the high wall.
The mighty wall defends against the searing sandstorms but has also blocked the spread of wisdom's blessing. Is divine wisdom not meant to shine on all people?
Port Ormos
The harbor betwixt the two trees.
"Bah! The lectures of the sages are beyond boring. Why don't we get ourselves some fine wine garnished with floral honey and set out on a journey across the seven seas?"
Sumeru City
The root of all wisdom on earth.
Under the luxuriant Divine Tree, the sages of the academy city have accumulated all the knowledge there is to be gathered. Welcome to Sumeru, O Traveler seeking answers.
Mawtiyima Forest
The forest of enormous fluorescent mushrooms.
Here, giant mushroom caps construct a canopy of light, obscuring the sun and the moon. Is this a man-made paradise, or a garden waiting to bloom?
Apam Woods
The forest of a rain without end.
The towering trees reach for the sky freely. Perhaps one day its branches will touch the stars. But under their canopy, the rain has never ceased.
