just as brok makes this decision , his eyes start to play tricks on him , so it seems to him ... for as he looks about the land he so covets , itfor one shuddering , shimmering momentbecomes not as a land of plenty and bustle , but a land of dryness , parched , a land without water ... land deserted and barrenwhere even the water is salty ... a land of great thirst ... as he rubs his eyes and shakes his head to look once again , so has this strange moment passed .
