Aesoland, with the place names left in conflict
Sources: mhoutlandersbuild map notes · Official site (English) · Official site (Japanese) · monsterhunteroutlanders.cc release time zones. Verification policy.
The island is Aesoland. Older notes also say Isolesia, and the Japanese site uses アイソレシア島. I do not have coordinates, camp pins, or a live map file.

Regions in the write-up
The smaller areas, apex placements and activity names below come from mhoutlandersbuild alone and remain unverified beyond that source. Giantwood is the wording on monsterhunteroutlanders.cc; Grand Archipelago is the wording in the map guide.
Five smaller areas are named: Outlands, Muddy Marsh, and Cloudmist Forest on the forest side; Oasis in the Sands and Great Sand Sea on the desert side. Field tools are catapult, wind platform, and zip line. Activities named are Zen Stone Balance, Winged Treasure Hunt, and Egg Heist Challenge.
Apex notes: Radiant Rathalos for the archipelago wording, Radiant Diablos for Searing Plains. A TGS 2026 note mentions a later area, Abyss of Decay. Ecological rank rises as you progress and monsters get stronger.
| Source wording | Areas named by the map guide | Evidence |
|---|---|---|
| Giantwood / Grand Archipelago | Outlands; Muddy Marsh; Cloudmist Forest | Names differ across cc release page and mhoutlandersbuild |
| Searing Plains | Oasis in the Sands; Great Sand Sea | Subareas: mhoutlandersbuild only |
| Abyss of Decay | Later-area reference | Historical TGS note, single map guide |

Questions
Is there an interactive map?
Not on this site. The source itself said no interactive map was available before launch, and I still do not have one.
