CryptWizard's Realm

Someone recently asked for help with a riddle that is in this Warcraft III map, so I took the effort to extract it, so I might as well put it somewhere that can be reached by Google.

Enjoy!

"Defenders of Greece, to The Black Road!"
"Demons! Lots of Demons. Here they come down the road."
"Demon attack is imminent!  Return to Athens at once."
"Scouts report demons approaching Athens on The Black Road!"
"Quick! The gates of Hades are opening near The Black Road!"
"I charm birds, fishes and wild beasts, coax the trees and rocks into dance.  Which one are you?"
"Leave me be. I'm one of the handful of Greek heroes to visit the Underworld and return."
"I only sing about dead heros now.  Guess it's about time to sing your song."
"Click me again, and I'll restring your face."
"Even in the darkest parts of underworld my song and lyre did not lose their power."
"The Orphic way of life: vegetarianism and abstention from sex, and refrain from eating eggs and beans."
"Now I know why Serius said you were an assclown."
"Alive without breath, as cold as death. Never thirsty, always drinking, Clad in mail, never clinking."
"fish"
"An army I am countless upon the battlefield, even over hills and valleys. My soldiers have uncountable blades at their disposal, yet not a single shield to count."
"grass"
"I have no voice, yet I speak to you. I tell of anything you'd ever want to hear. I have leaves, but I am not a tree. I have a spine and hinges, but I am not a man or a door."
"book"
"What has roots as nobody sees, and is taller than trees. Up, up it goes, and yet never grows?"
"mountain"
"When I am young I am tall, When I am old I am short. While I have the light of life, The breath of god is my foe."
"candle"
"What can run but never walk, Has a mouth but never talks? Has a bed but never sleeps, Has a head but never weeps?"
"river"
"What is greater than Zeus, more evil than Hades. The poor have it. The rich don’t. If you eat it you will die."
"nothing"
"My first is in water and also in tea. My second is in fish but not in the sea. My third is in mountains but not underground. My last is in strike but never in pound. My whole crushes mountains, rivers, even civilizations. And all that live, fear my arrival."
"time"
"The beginning of eternity, the end of time and space. The beginning of every end, and the end of every place."
"e"
"What is the animal that has one voice, and goes on four legs in the morning, two legs at noon, and upon three legs in the evening?"
"human"
"Carrying a scythe, I arrive when I should, always behind but never late.  I hold in my hand what never stops moving."
"fathertime"
"Feed me and I live, give me drink and I die. A little air and I grow, too much and I go away."
"fire"
"I raise my weapon up to the sky; I let my armies fall and fly; I let my weapon strike the ground; and let loose a terrible battle cry."
"storm"
