Fantasy Castle in Mysterious Landscape

A lush jungle where elves live in harmony with nature, building their homes on the branches of giant trees. The jungle is full of magical beasts, such as unicorns, griffins, and phoenixes. But it also hides dark secrets, such as ruined temples, bloodthirsty cults, and demonic portals.
A frozen tundra where dwarves mine for precious metals and gems in the depths of the snowy mountains. The tundra is also the domain of frost giants, ice dragons, and yetis. The dwarves must defend their fortresses from the raids of these ferocious foes.
A stormy sea where pirates sail the seven seas, looking for treasure and adventure. The sea is also the realm of merfolk, sea monsters, and ghost ships. The pirates must brave the perils of the waves, the wind, and the whirlpools.
A mystical forest where fairies dance in the moonlight, sprites play in the streams, and nymphs sing in the flowers. The forest is also the source of powerful magic, such as enchanted weapons, spells, and potions. But the forest also harbors dangers, such as wicked witches, evil wizards, and rogue knights.
