I cannot prove that gods do ...

I cannot prove that gods do not exist. Nor can I prove that the world and everything in it was not created by an entity or entities in the distant past. But I can tell you that in the millennia we elves have studied nature, we have never witnessed an instance where the rules that govern the world have been broken. That is, we have never seen a miracle. Many events have defied our ability to explain, but we are convinced that we failed because we are still woefully ignorant about the universe and not because a deity altered the workings of nature.

That requires imagination and thoughtfulness, and it is those qualities that the best warriors share, even if, on the surface, they appear completely different.

A true warrior does not fight because he wishes to but because he has to. A man who yearns for war, a man who enjoys his killing, he is a brute and a monster. No matter how much glory he wins on the battlefield, that cannot erase the fact that he is no better than a rabid wolf who will turn on his friends and family as soon as his foes.

They enveloped each other within the folds of their thoughts, holding each other with an intimacy no physical embrace could replicate, allowing their identities to merge once again. Their greatest comfort was a simple one: they were no longer alone. To know that you were with the one who cared for you, and who understood every fiber of your being, and who would not abandon you even in the most desperate of circumstances, that was the most precious relationship a person could have, and they both cherished it.

Saphira waved her tail, the tip whistling loudly. "I'm not asking you to. However, if we attack first, we may gain the advantage." "Have you gone crazy? They'll..."
