Knagis: I suppose it's time.
Thank you to all who found the horse and solved this mystery. Initially I had thought that this will be a week long experiment that will be archived very quickly. But turned out that people did like the task - the main idea in it being that one cannot find the information online by themselves but rather have to find someone who knows horses to identify at least the breed, most likely find someone who knows where that horse lives and as a last step most people had to call or visit the stable to find out the name. So overall a lot of human interaction unlike most other tasks.
For those that didn't find the hero of this task - he is a Shire horse, named Ace of Spades and lives in Erceni stable in Kalngale.
