Though it does take a lot of time to explore every single area in the world map, it isn't all that big or complicated to understand.
The bottom of the map is the starting area, with the first four titans . The lava biome and the snow area are both on the left. The Elder, a biome on its own, is located on the right. The rest of the titans are found in the center of the map, except the last three, who can be found in the temple at the very top of the map.
