You can launch the editor from the main menu under "Advanced".
In Heroes of Might and Magic: Olden Era, the map editor is a tool for creating custom maps within the game. It allows you to create your own scenarios by customizing the map, placing objects, cities, resources, neutral creatures, roads, zones, and other elements of an adventure map.
Since the game is in Early Access, the editor should also be considered as an early version of the tool, rather than a fully completed system. Its primary task at this stage is to provide the ability to create and test your own maps, as well as expand the amount of user-generated content beyond official scenarios.
Currently, the editor focuses on creating maps, not on full-fledged modding of the entire game. This means that it is primarily designed for working with the map and its contents: landscape, objects, starting positions, neutrals, resources, and the overall structure of the scenario.
At the same time, do not confuse the map editor with a tool for deeply changing the game mechanics. In its current form, it is not a complete platform for creating new Factions, units, artifacts, spells, models, music, or global game rules. Such features either do not belong to the basic purpose of the editor or may depend on future updates.
In Early Access, the editor can be seen as part of the main set of Olden Era features. Along with official maps and modes, it should help the Community create their own scenarios and share them. However, like the game itself, the editor may still change: its interface, feature set, stability, and map compatibility may be improved as the project develops.
