The complex Aiel code of honour and obligation, literally 'honour and obligation' in the Old Tongue. Ji'e'toh governs nearly every aspect of Aiel life, from warfare to personal relationships. Central concepts include toh (obligation or debt of honour), which can be incurred through actions or failures, and ji (honour), which is gained through meeting one's obligations. Understanding ji'e'toh is essential to understanding the Aiel, and most outsiders find its intricacies bewildering.
