The wargs had caught up with them, and they were now trapped to the tree. The monsters had ceased their growling, then turned as the white warg, with Azog on its back, approached. 

Azog smirked cruelly, he seemed to take delight in seeing Thorin's shock. “Do you smell it? The scent of fear?" The Pale Orc stroked his warg with his hand, and then his steely gaze matched Thorin's as he spoke in black speech. “I remember your father reeked of it, Thorin son of Thrain."

“That one is mine." Azog faced his mini army as he sent them to attack. “Kill the others!"
At his command, the Wargs ran forward and tried to climb the trees. They jumped as high as they could, clawing
at the tree trunks and breaking apart branches in their jaws. The trees shook violently at the assault, and the company struggled to hold on.
"Drink their blood!" Azog's attention was drawn to Saeril, and recognition showed in his eyes. During the days of her corruption, she had sent him to cause destruction upon Moria. 

"Do you have further orders?" This was a taunt, for Azog knew of her crimes, and he made sure that she was reminded of them. The she-elf screeched at the Pale Orc's taunt before she shouted Black Speech to the creatures. After this action, the winged elf aggressively collided and toppled one of the warts who tried to climb a tree, toppling it over the cliff. Knowing that it wasn't over yet, the female made a u-turn, and charging back to hit one of them head-on. 

Thinking quick, Gandalf retrieved a pinecone, and conjured blazing fire upon it. "Fili!", he passed one down to the eldest prince below, as well as the others, and throwing the blazing object at the creatures, creating a trailing wall of fire to get them away from the tree.
