"A group of four, including a black knight and three guardians

"A group of four, including a black knight and three guardians, navigating through a dark and foreboding landscape. The scene is set in a desolate land with treacherous mountains and murky swamps. The sky is perpetually dark, with low visibility. The black knight is leading, and the sorcerer named Valis uses his dark powers to illuminate their path. The atmosphere is tense, and Valis shouts a warning as ominous shadows emerge from the darkness, suggesting imminent danger. The style is dark fantasy with high contrast and dramatic lighting."
