Ages ago, sorcerers of unmatched power sundered a world into four realms--sky, stone, fire, and water--then vanished. Over time, magicians learned to work spells only in their own realms and forgot the others. Now only the few who have survived the Labyrinth and crossed the Death Gate know of the presence of all four realms--and even they have yet to unravel the mysteries of their severed world. . . .

 

In Arianus, Realm of Sky, humans, elves, and dwarves battle for control of precious water--traversing a world of airborne islands on currents of elven magic and the backs of mammoth dragons. But soon great magical forces will begin to rend the fabric of this delicate land. An assassin will be hired to kill a royal prince--by the king himself. A dwarf will challenge the beliefs of his people--and lead them in rebellion. And a sinister wizard will enact his plan to rule Arianus--a plan that may be felt far beyond the Realm of Sky and into the Death Gate itself.

死亡之門系列－千百年前，法力無可匹敵的大法師們將世界撕裂成四個界域：空、石、火與水之界，然後就此消失。隨著時光流逝，後世的法師只能學會他們自己界域的法術，而忘了其他魔法的存在。到如今只有少數活過迷宮考驗，並且穿越過死亡之門的人知道全部四個界域的存在--即使如此，他們也尚未揭開這世界分裂的謎團

 

龍翼在艾瑞亞那斯，也就是空之界域裡，人類、精靈與矮人乘坐在巨龍的背上與精靈魔法船，穿梭在這個由大小浮島所組成的世界。就在他們爭奪寶貴水資源掌控權的同時，暗地裡一股強大的魔法力量正悄悄成形，即將橫掃這些脆弱的領土。刺客密謀暗殺王子，主使者正是國王本人；一名矮人將挑戰他們亙古的信仰，並帶領族人邁向革命；邪惡的巫師將實踐他統治艾瑞亞那斯的計畫-影響所及將不只限於空之界域，亦將深入死亡之門。
