They returned to the three tunnels before the horse walked inside the tunnel it once appeared from without hesitation. The tunnel was so big, almost fifty meters wide.
So Arthur didn't find any problem running beside the horse.
Just after ten minutes Arthur found the tunnel getting wider until it ended up in a gigantic underground cave that extended for miles.
The ceiling was so far high up, almost half a mile above his head. Long and thick rocks extended from it like different sized spikes, and the ground was filled with different ores that were enough to lighten up the entire cave with orange and brown light.
And in the center of this vast place Arthur spotted a group of small horses compared with the giant one on his side.
And they were lying weakly beside the body of another horse that seemed to be not moving.
"Is she… the mother?" Arthur muttered in deep shock while he realized what was going on.
