"A chaotic, high-fantasy battleground inspired by Summoner's Rift, bathed in ominous shades of blue and shattered crystal formations scattered throughout the environment. The scene is dominated by a ruined terrain where towering crystalline structures lie fractured, their glowing blue cores pulsating faintly amidst the wreckage. The ground is cracked and uneven, with sharp crystal shards protruding from fissures, emanating ghostly light. Dark, twisted trees with glowing blue veins frame the edges of the battlefield, adding an eerie atmosphere. The river running through the landscape is turbulent, reflecting the chaotic energy of the environment, and faint mist rises from its surface. The sky is overcast, with streaks of blue lightning illuminating the scene sporadically. Floating debris and shimmering particles add to the sense of destruction and instability. Cinematic lighting with intense contrast highlights the dramatic and mystical nature of the setting, drawing the viewer into the chaos." Emphasize shattered crystals by making them the focal points, with glowing shards scattered dynamically. Add glowing runes or magical effects to enhance the mystical and chaotic atmosphere. Use dark blues, turquoise, and subtle purples for a cohesive, otherworldly color palette.
