Throne of Glass; The Task from Nehemia

Nehemia's request

Nehemia. Nehemia the brave. Nehemia the clever and beautiful. Celaena's one and only friend who was stabbed by Grave only a few months before. Celaena should have been used to the presence of a ghost because of Elena but seeing Nehemia made her feel as if the empty hole in her chest had returned. An uncontrollable sob wreaked throughout Celaena's body.
Nehemia glided towards Celaena and put her arm gingerly around her. Celaena felt she had had a bucket of icy water chuck over her.
"Shh, Elentiya I have not come here so you can mourn me." said Nehemia quietly. "We have preciously small time together as I cannot distract the gate keepers for long."
Celaena stifled her sobs and listened.
"There is something I need you to do, Elentiya, that I had not been able to do due to my death. Celaena looked at Nehemia and saw a long thin knife cut just across her chest. She grimaced.
"I need you Elentiya to go to the land of my people and warn my mother and father as I believe there is to be an incoming invasion. I do not know when but the spirits are unrestful and I fear the King may be using the Wryd Marks to call up an army." Nehemia's voice quivered, "You must stop him, Elentiya. Please. He is going to kill my family."
Nehemia looked at Celaena for a long time; a sad look in her eyes. "This will be the last time I will see you." she said and was gone.

Celaena stared at the spot where Nehemia had just been. She hadn't even had had the chance to tell her she would do it. Or how she was so sorry for everything. How she should have been there the night Nehemia had been murdered. She willed herself to be strong. What had Nehemia thought of her when she had burst into tears? Celaena didn't want to find out. I will not be afraid she thought to herself as she started to climb the stairs back up to the world of light and life.
