Giants come in various sizes, but most of them are at least twice as tall as humans. The tallest giants were said to grow as tall as the trees. Besides their magnified features, they look like humans.
Long ago the giants ruled the High Kingdoms, with the city of Duplovia as the center of their culture. But then the humans from the Low Kingdoms came and vanquished nearly all of them, building a new city on top of the ruins of Duplovia. The remnants fled to the mountains, where they keep to themselves, for humans still regard them as a threat due to their size. It is unknown how long a giant can live.
