The Waste Land at Wikipedia

The allusion is to the wounding of the Fisher King and the subsequent sterility of his lands. To restore the King and make his lands fertile again the Grail questor must ask “What ails you?”

From Ritual to Romance

Weston’s book is an academic examination of the roots of the King Arthur legends and seeks to make connections between the early pagan elements and the later Christian influences. The book’s main focus is on the Holy Grail tradition and its influence, particularly the Wasteland motif. The origins of Weston’s book are in James George Frazer’s seminal work on folklore, magic and religion, The Golden Bough, and in the works of Miss Jane Ellen Harrison.

Wasteland mythology

The Wasteland is a Celtic motif that ties the barrenness of a land with a curse that must be lifted by a hero. It occurs in Irish mythology and French Grail romances, and hints of it may be found in the Welsh Mabinogion.

In the Arthurian Grail material, the Wasteland’s condition is usually tied to the impotence of its leader. Often the infirmity is preceded by some form of the Dolorous Stroke, in which the king is injured tragically for his sins but kept alive by the Grail. In Chrétien de Troyes’ Perceval, the Story of the Grail, the Fisher King has been wounded in a misfortune that is not revealed in the incomplete text, and his land suffers with him. He can be healed only if the hero Perceval asks the appropriate question about whom the Grail serves, but warned against talking too much, Perceval remains silent. In the First Continuation of Chrétien’s work, the anonymous author recounts how Gawain partially heals the land, but is not destined to complete the restoration. Over the course of time romances place less emphasis on the Wasteland and more on the king’s wound. In the Lancelot-Grail Cycle the link between the devastated land and the wounded king is not absolute, and in the Post-Vulgate Cycle much more emphasis is placed on King Pellehan’s injury by Sir Balin than on the devastation this causes to his kingdom.
