His own blinding confidence aside in his people, Ganondorf had chosen it to be done quietly for a number of reasons: For all of their posturing and absurd looks, Gorons were enormously strong as a people, and he was not looking forward to an extended conflict with the Goron on their own territory, they could practically hear every noise of the mountain if they focused hard enough. This was supposed to be quiet for practicality, and for curiosity.
Never in any times that he had returned to Hyrule, had Ganondorf ever once sensed his ancient blade within arms reach. It was a long, distant memory that triggered feelings and thoughts that he wasn't sure were his, or what he used to be. Without his triforce piece, the Gorons would be a very dangerous threat even to him in numbers...of course, that could be said for anyone. This was not an easy task by any stretch of the imagination, the Goron city was built directly into the mountain, they would be traversing over rooftops and walking in front of houses, there was no other real choice in the matter. All they had to go on was his on feeling of what he was looking for. It was not an easy task to do so, but Ganondorf would give Sybil and her warriors credit, they stalked like huntresses across the shadows, and he felt like he had become a child again following after his sisters.
They went deeper, and deeper into Death Mountain, following the flow of lava, noting that the Gorons had made some manner of irrigation system with the natural stone. The houses gave way to nothing but barren rock and sweltering heat, but he could feel it, following the lava that dipped down into an opening, his sword was there, crackling powerfully with dark energy as old as the mountain itself. Ingenious indeed, they were trying to drown his blade in lava, but the crackling energy around it kept it at bay. It was a slow, arduous process.
"Magnificent..." Ganondorf purred hungrily. It was like seeing an old friend again, no doubt it was taking all of his focus to stay alive.
