Within the game you will initially only control yourself, a summoner. You should set out to both influence the physical realm around you (the map) and begin practising your control over the elements.
The map is a hex-based representation of each plane (or world). Each plane's map is 2d - flat, but there are multiple maps, each representing a layer or different plane. Each map rarely connects directly, but has connection points when a portal allows travel between. Each hex on the map represents an area of terrain, marked visually by the most dominant scenery - mountains, river, forest and so on. If you have domination over an area, it will be marked by your icon and contributes to your power (creatures and essence).
The elements have a very free-form system of development. Everything is broken down to the basic costs of each element, but the recipes for creation (or destruction) must be invented or discovered.
