AUTHOR'S NOTE: This story has gone through a major revision and I'm working on a new translation now.

Aitana Pones, an archaeologist whose theories are considered "nonsenses" by the historian community... or at least that's what it looks like. When her investigations and artifacts show that a huge dark power may be rising in the desert of the Wolf Kingdoms she rushes to investigate. There, she will meet an slaved mare that hides many secrets, and both will realize that they are racing against time itself...

Original spanish story can be found in fanfiction.net. The same author, Volgrand (that's me!) is translating it to english.
