Dragon Age: Origins is a beautifully rendered fantasy role-playing game with medieval European visualization for the game art direction. Combat is bloody and gruesome, filled with spraying blood and decapitation, but also stylized with special finishing blow animations. The game has various Downloadable Content adventures, items, and small expansions; and one major expansion/sequel, "Awakening".
This page of fantasy game art from Dragon Age: Origins features Wild Sylvans: Trees possessed by rage demons or, sometimes, a less hostile spirit (resulting in a less hostile Sylvan, such as The Grand Oak). The Awakening expansion adds Charred Sylvans.
From Codex entry: Wild Sylvan:
... Slow but immensely powerful, wild sylvans prefer to lay in ambush, waiting for a victim to become lost, tired, or trapped before closing in for the kill. They hide among regular trees, nearly undetectable until they begin to move and to reach. When they do "come to life" as some travelers say, they stand tall, roots forming into legs and feet and branches stretching out into lashing arms.
When not presented with a living target, however, it has been noted that sylvans often fall into a form of dormancy, perhaps brought on by the nature of their tree host. While mobile, they normally return to wherever they were rooted once their prey has been killed. For both these reasons, a forest that has sylvans within can become incredibly dangerous to pass through for very long periods of time.
... On rare occasions, demons possess trees almost completely destroyed by fire but that still retain a spark of life. This union often rekindles the fire that first damaged the tree, resulting in a sylvan that burns continuously without being destroyed.
