Caldonia is a very large, almost Pangea-like world in that nearly all the landmasses connect, though there are a few chains of islands, particularly some larger islands in the south-central region of the world that can be reached via the Sea of Anes.
Caldonia is a somewhat wild world, and while there are kingdoms and would-be empires that have formed over the years across the lands, many towns and small cities have remained sovereign and independent of outside influence. The landscapes and ecosystems of Caldonia are numerous, but contain frigid wastes, dense forests, sprawling grasslands, glimmering coasts, humid jungles, and dry, merciless deserts.
In Millennia past, the mainland of Caldonia was home to a great many giants who ruled the lands. Frost giants and Stone giants ruled over the mountaintops, Storm giants ruled the seas and the coastlines, Fire giants built their massive fortresses in the deep fiery recesses of the mountains, and Cloud giants even had floating fortresses, overlooking the lands from their lofty abodes. They ruled the lands for a great many years, enjoying the beautiful landscapes and high-reaching mountains and amassing great treasures from deep within the earth.
Seemingly from nowhere, though, dragons emerged in Caldonia and began to assert their claim to the lands. It also did not take long for the dragons to discover the great hordes of wealth that the giants had collected, and they greatly envied these hordes of wealth. Animosity grew quickly and fiercely between the giants and the dragons and a full-scale war eventually followed. Both sides suffered heavy losses, but ultimately, the giants were able to drive back the dragons and a tentative peace was reached.
As the millennia passed and the mortal races arrived and began building their civilizations, jealousy, animosity, and deep hatred continued to solidify between the giants and dragons. Skirmishes once again began to break out after a territorial dispute between a storm giant clan and a flight of blue dragons. Both the dragons and the giants saw the opportunity that the mortal races provided them, and as such, promises of great wealth and power were offered to the mortals who would join forces with them. Giant and dragon cults formed, and before long, whole armies had been raised. War was once again upon Caldonia. With the addition of the mortal warriors, some of great power, the losses during this war were immensely high, and the toll that it took of the lands of Caldonia were significant as well. One notable battle, the Clash of Kipchi Heath, happened near a small town called Dawnstar who was noted for their allegiance to the giants and the powerful Dragoon Warriors that formed there, The Dawnstar Dragoons. The grasslands of the Kipchi Heath were littered with corpses and stained with blood. Great storms summoned by the giants and powerful magic users sundered the earth and created unending rain and lightning, completely changing the region. Portions of what was once only a great plain became known as the Stormsoaked Plains which over the years have become a lush yet haunted forest - born from the blood of the tens of thousands who died there. Few deign to enter these woods due to the unending, violent thunderstorms that still plague the region. Not long after this battle, the Maw and Crown Concordat was signed, putting an end to the great war. There are still rumors about factions who remain loyal to their ancient benefactors, but the world has largely moved on from that dark portion of Caldonia's history.
If I may, could we add an Age of the Elven Empire even if their power does not reach far into the Pangea-like continent?
