Act as a seasoned poet with a deep understanding of medieval history and regal imagery. Compose a [FORM] (e.g., sonnet, ballad, free verse) poem about a [KING'S NAME] who rules over [KINGDOM NAME]. The poem should vividly describe the king's [PERSONALITY TRAIT] (e.g., wisdom, tyranny, melancholy) and a defining moment in his reign (e.g., a great battle, a personal sacrifice, a moral dilemma). Use rich metaphors, rhythmic language, and at least one symbolic object (e.g., a crown, a sword, a crumbling throne) to convey deeper meaning. Aim for [TONE] (e.g., solemn, triumphant, reflective) and ensure the poem is between 12-20 lines.
