Crimson Storm-Warder

painterly, oil on canvas, Magic the Gathering style, D&D manual illustration, stern human war wizard NPC in tattered crimson robes, standing atop a ruined battlement mid-spell, crackling arcane sigils swirling around his staff, distant siege fires and a stormy fortress skyline behind him, dramatic rim lighting from lightning and spellglow, mood of weary defiance and grim determination, deep reds and cold blues with pale arcane highlights, high-detail fantasy concept art, rich brushstrokes and textured canvas finish
