Of course, the following is the polished version to make the language more emotional and literary: **Original sentence: ** Half-human, half-Atlantean Arthur Curry is taken on the journey of his lifetime to discover if he is worth of being a king. **Helping version: ** Arthur Curry, caught between two worlds as the son of a human and a queen of Atlantis, embarks on a defining journey — not just across land and sea, but deep into his own soul — to uncover whether he is truly worthy of the crown fate has placed upon his head. If you have a specific style (such as movie slogans, novel openings, advertising copy, etc.) or purpose (such as posters, trailers, social media promotions, etc.), I can also further adjust to suit your needs.
