Romans web Alternate World

Alternate-world novels on Tellura include isekai (protagonist transported to another world), transmigration (consciousness inserted into a body in another world), and pure secondary-world fantasy. The defining feature is that the setting isn't ours.

Worth reading as a parent tag: isekai transports a person, transmigration relocates a consciousness, and secondary-world fantasy just starts there with no earthly reference at all. The reading experience differs a lot, an isekai protagonist can compare, a native cannot. Filter to isekai specifically if you want the outsider's perspective.
