Struggle and futility- each day is a battle to keep life's embers burningfor one more night. The leper embraces this solid truth. A tortured existence has taught him to rely only on himself, turning his energy inward, forging a kingdom of resilience within. His strength serves neither to heal nor aid but to endure beyond human limits. And when his blade falls its thunderous ark tolls deaths call for all within it
