Ikarus 是哪個國家

Alexander, using the power of Ikarus, became the only one who knew the country's deepest secrets and was called the 'richest man in the world', but it turned out that his twin brother was also Ikarus. Bold, cunning, and greedy, he hails from Eastern Europe and is a former intelligence officer. He enjoys collecting rare artifacts and playing chess, but dislikes bureaucracy and incompetence. His life experiences include living in multiple countries and studying ancient history, and he always carries a leather-bound journal.
