Fantasy
A mage flinging lightning and death spells faces off against an ancient dragon whose fiery breath has seared whole armies. A knight bedecked in bright armor rides forth with the sunrise and the kingdom's acclaim, sworn to a worthy quest that might last years. A party of travelers, swords sheathed and bows unstrung, enters a firelit inn just before the evening rain hits, drawn by the smell of roast beast and delicate notes from a song performed by an elven bard. A band of explorers descends into a sprawling, buried ruin left behind by vanished forerunners, eager to find treasure and magic.
The fantasy genre is an exploration of worlds where magic exists side by side with untamed forests and expansive mountain ranges that are home to elves, dwarves, and other mythical creatures. The mostly preindustrial societies dotted across the landscape often feature newer, human societies, while much older humanoid species (and monsters of every sort) are everywhere else, save those that are long vanished, leaving behind their mysterious ruins to lure the curious.
Which means you can expect your character to embark on quests, confront supernatural threats, and grapple with themes of destiny, power, and good versus evil. And you'll do so wielding magic, enchanted tools and weapons, and extraordinary special abilities of your own.
