The sound of drums that had been silent for years roared loudly enough that even as he stalked to hallways of the palace with his false knight following him, Grindan could hear them. As they passed by a window pointing towards Castle Town, Grindan turned his head and paused long enough to look over the smoke and carnage to see what the drums had already told him; A large cloud of dust was being kicked up outside of the walls. The goron had arrived and they had arrived in numbers. 

The former King likely would have been greatly relieved to discover that his information on the current status of the goron had been incorrect, but Grindan couldn't make a judgement call on the state of the goron forces about to join the fight solely from the dust cloud they had kicked up. Ganondorf had informed him that the Goron had been cut off from their food supplies and had been forced into a state of famine. They [i]might[/i] have overcome the dangers that had blocked them off from their food in a timely manner and be in the process of recovery, but this also could be the final charge by a doomed people seeking a quick death on the battlefield rather then to slowly waste and rot away to starvation and plague. 

Regardless, the goron were not currently [i]his[/i] problem. Turning away from the window, he increased his pace to make up for lost time and locate the Queen as soon as possible. A small part of him couldn't help but take a dark sense of amusement from the fact that as he passed by the odd person in the halls, the fact that his armor was splattered with fresh blood while the axe he carried was still dripping with the stuff wasn't a cause of alarm once they recognized who he was. It wasn't like this was the first time he had been seen in such a manner after all. Even if his own dark reputation hadn't proceeded him there were a few additional facts in his favor. There was a battle actively being fought for starters and he was dressed for battle in kind. The fact that he was traveling with an armored knight (all be it a lesser one without heraldry on his shield) who was also splattered in blood suggested that they had seen combat which... to be fair was true. 

The lack of foot traffic in this part of the castle did help him avoid having to answer the awkward question of why two warriors who had clearly seen combat already was heading towards the royal living area. Sure there were plenty of lies he could offer that would sound convincing and send them on their way if he didn't just decide to cut them down where they stood, but the interruption would still have been a hassle.

He needed to find the Queen and fast... if for no other reason then so he could hunt down Princess Zelda and find some relief from the his concerns that the Stalfos he had sent to do the task of either bringing her to heel or killing her had not been up to the task. Yes, Impa was a formidable foe and fiercely protective of the young Princess, but they should have had the element of surprise and as he had proven earlier, the traitor's hand struck with the might of a legion. 

It was a problem to be concerned with later. Right now he had a Queen to find.
