Prologue - Clandestine Activities
Many stories of the eternal battle over the Triforce were recorded in the annals of Hyrule's history. This particular one was a little irregular and frankly, embarrassing. It started in a pasture.
It was still a few hours until dawn and the group of elite soldiers in the service of Lord Ganon were getting annoyed. There was a ritual uncovered recently which had interested Master Takeshi immensely. By performing the ritual in the place where Ganon had fallen, they would be able to call upon the residual dark energies which lingered in the ground.
The problem with this was that they didn't know precisely where in Hyrule Field the fight had finally ended. The witnesses at the time had been vague about the whole thing. People were less concerned with Ganon's majestic majesty, and more concerned with the blasts of malice and light which had been flying about the place. No monument had been erected at the time and Zelda hadn't left any visible trace of where she'd completed the banishment. They searched for where Ganon's grave might be but-
-A blademaster's foot sank into something soft and decidedly not grass. The stupid civilians had put a ranch in this particular location. They'd tried the ritual in various likely places which could have been Lord Ganon's resting place. This included storerooms, roads, cucco huts, forests, and in one very memorable instance a little boy's hideout. The blademaster suppressed the urge to murder the horse responsible for this insult to his footwear. Sneaky ninjas were not supposed to dirty their blades on simple animals.
"Are you going to get on with the ritual? We cannot keep Lord Ganon waiting," spoke the scowling blademaster. It was impressive that he managed to convey the scowl so well even with the mask concealing his face.
"This is important and will not be done improperly. Mind that step right there." The shorter figure in red and black robes pulled out a scroll and did his best to ignore the mooing from the barn a few feet away. Dark chanting began to issue forth from that particular masked figure which was almost sinister enough to counteract the un-sinister effect of the cow.
The third and last figure said with a quiver in his voice, "If we fail, we are going to be punished by Master Takeshi." Then came the afterthought, "...and have failed Lord Ganon." The three did not want to admit what failure would bring. Master Takeshi had decided to stop wasting time on this fool's errand but the three had decided to try to take initiative for the tantalizing prospect of advancing in the ranks. Yiga masters did not really like their underlings thinking for themselves so they would likely be demoted.
The night wore on and it got really boring after forty-seven minutes of ominous incantations.
The three were surprised when things suddenly stopped being boring. A little dark energy suffused the air like scent from a freshly opened can of cat food. The sorcerer jolted and recomposed himself. He stood up straighter. Now all he had to do was name the servant which would herald the return of the Scourge of Hyrule. His shoulders changed from the outline of a child which knew he was grounded to the shoulder outline of a future chancellor. Cows mooed and horses began to spook but he would not be deterred.
"Great Ganon! Send us your monstrous children! Let them take on a form most powerful to strike fear into the hearts of the cowardly enemy!" His mind went blank and he stuttered again as he looked at the scroll. The caster considered what monster it should actually be. They hadn't really rehearsed this part. "Send us a-a-like-like lynels. Send us lynels!"
The darkness surged. From the home of the ranchers they heard a commotion. They ignored the shouting of the farmers as they were too busy watching rupees spring forth from the soil around them. That was not expected whatsoever. As a rule, if you do a blood ritual in the middle of the night and ask for monsters, you don't get money. Sometimes you do blood rituals in the middle of the night for money and get monsters but no one ever heard of the reverse happening.
The rotund owner of the ranch in question sprang from the door with sword and shield at the ready. He was a man on a mission to stop cattle rustlers from undermining society. This noble heroic man was stopped by the same glittering sight as the Yiga. "What in tarnation?... he said as his mind slowed to a halt in light of the money sprouting from the grass. His foot brushed a rupee. A loud squelching noise caught his attention and he let out a rather unmanly shriek as the giant slug thing erupted from the ground.
He survived; The shield did not.
On the whole, Hyrule would have preferred the lynels.
