Q: Passage: It is not clear why, in 1873, Alkan decided to emerge from his self-imposed obscurity to give a series of six Petits Concerts at the Érard piano showrooms. It may have been associated with the developing career of Delaborde, who, returning to Paris in 1867, soon became a concert fixture, including in his recitals many works by his father, and who was at the end of 1872 given the appointment that had escaped Alkan himself, Professor at the Conservatoire. The success of the Petits Concerts led to them becoming an annual event (with occasional interruptions caused by Alkan's health) until 1880 or possibly beyond. The Petits Concerts featured music not only by Alkan but of his favourite composers from Bach onwards, played on both the piano and the pédalier, and occasionally with the participation of another instrumentalist or singer. He was assisted in these concerts by his siblings, and by other musicians including Delaborde, Camille Saint-Saëns, and Auguste Franchomme.Those encountering Alkan at this phase included the young Vincent d'Indy, who recalled Alkan's "skinny, hooked fingers" playing Bach on an Érard pedal piano: "I listened, riveted to the spot by the expressive, crystal-clear playing." Alkan later played Beethoven's Op. 110 sonata, of which d'Indy said: "What happened to the great Beethovenian poem ... I couldn't begin to describe – above all in the Arioso and the Fugue, where the melody, penetrating the mystery of Death itself, climbs up to a blaze of light, affected me with an excess of enthusiasm such as I have never experienced since. This was not Liszt—perhaps less perfect, technically—but it had greater intimacy and was more humanly moving ..."The biographer of Chopin, Frederick Niecks, sought Alkan for his recollections in 1880 but was sternly denied access by Alkan's concierge – "To my ... enquiry when he could be found at home, the reply was a ... decisive 'Never'." However, a few days later he found Alkan at Érard's, and Niecks writes of their meeting that "his reception of me was not merely polite but most friendly.". 
Question: Whose reception of Niecks was reportedly not merely polite but most friendly?

A: Alkan.

Q: Passage: The remaining vampire covens are on the verge of annihilation by the Lycans. Both species are searching for Selene: the vampires seek justice for the death of Viktor, while the Lycans, led by Marius, intend to use her to locate Eve, whose blood holds the key to building an army of vampire-werewolf hybrids.
Semira, a council member of the Eastern Coven, tells Thomas she wants Selene to be granted clemency and to train the coven's neophyte Death Dealers. She asks Thomas to plead Selene's case before the full council; the plea is successful and the council reluctantly agrees to a pardon in exchange for Selene's help. Selene arrives with David. Semira has Varga, her ally and lover, poison Selene and slaughter the trainees, framing Selene for the atrocity. With Selene in her power, Semira begins draining her blood, which she intends to drink to steal her power. Thomas and David attempt a rescue, but are attacked by Semira and Varga. Thomas is killed, but David and Selene escape.
The pair takes refuge at the Nordic Coven, pursued by Alexia, an Eastern Coven vampire dispatched by Semira. At Var Dohr, the Nordic Coven stronghold, Elder Vidar reveals that David is the son of High Elder Amelia, and thus the legitimate heir to the Eastern Coven.
Meanwhile, Alexia has told Marius, who is secretly her lover, that Selene is going to the Nordic Coven. Marius and his Lycans attack that coven. Selene and David fight alongside the Nordic vampires, who are led by Vidar's daughter Lena. Selene engages Marius in single combat, but he is too powerful in werewolf form, and she is stabbed by Alexia. Marius demands to know Eve's location, but Selene insists she does not know; Alexia confirms this after tasting blood from her sword. Marius sounds the retreat. Selene deliberately slides herself under the now broken ice of the lake, telling herself that this is the 'path'. 
Question: What are the first names of the people who take refuge at the Nordic Coven?

A: David.
