Legolas already shot down at least ten Orcs and Goblins before spotting one more going for the dwarf. Giving an almost-amused smirk, the Elf Prince brought up his bow once more, drew back the string, and aimed at the creature, letting the projectile take its mark...through the back of its skull. 

Saeril was already killing an Orc before her when she suddenly heard the distressed voice of Yavanna yelling for her aid. Having to knock the creature's dead body to the side, the winged she-elf depended on her hearing to guide her to where she heard the princess' voice. Gritting her teeth together in anger, she twirled her daggers while letting her senses take her over towards the two she-elves, the Orc, and Kili. Having to see the giant spike being aimed at the dwarf, the guardian charged, giving a piercing screech, towards Bolg. [i]'For the Sons of Durin'[/i] the elder thought, until she knocked the wind out of the assailant, pushing him off the cliff, in the process. However, she didn't notice Yavanna taking the fall with him. She cursed in Elvish, before taking the sight of the blonde elf in the distance. "Legolas!", she called out. 

When he heard the voice of the she-elf, the prince turned around, just in time to see Yavanna tumble down and land on one of the lower levels, appearing limp after the fall. Looking further down, he took notice of Bolg advancing towards her. Hoping to knock him off course with one of his arrows, he reached back for said-artillery but froze when coming to realize that he used them all up when defending Thorin. Throwing the bow aside, he sheathed his sword and jumped upon a troll that was trying to knock down the tower down earlier. Piercing it through the head, he guided him into ramming the tower, forming a bridge that would allow him an easier path to reach Yavanna. However, he was intercepted by Bolg along the way, just as the structure began to crumble. Legolas' weight was very, very light, so he wasn't disturbing any of the stones below his feet. Bolg, on the other hand, was way too heavy, causing him to fall to the level below the surface. 

From atop on the icy falls, Thorin was battling it out with the remaining Orcs but loses his sword during the fight. So, Legolas, looking down at the elf sword in hand, throws his sword into the Orc’s chest, practically giving Orcrist back to him. 

It was only for a moment that Bolg disappeared until he manages to reappear, having to get back to the Elf Prince's level. Taking out his dual knives, he battles it out with the giant Orc, until he manages to climb onto his shoulders and drive one of his blades into Bolg's head. As the tower was about the crumble, Legolas drew back his dagger, and let the Orc's body fall with the structure. Having to make it to the end, he looked around for the princess. "Yavanna!", he called out.
