"When mortals die, they have family, friends, compatriots to mourn them. When the land dies, all else dies with it, and there is no one left to weep." —Jacinth, Skyshroud ranger
"They groaned, they stirred, they all uprose, Nor spake, nor moved their eyes; It had been strange, even in a dream, To have seen those dead men rise." —Samuel Taylor Coleridge, "The Rime of the Ancient Mariner"
