None of the named NPCs rescued in the first two quests were auctioneers, and most of them are factually important and contributed to Warcraft’s story in their own way, shapes, and forms. It is misidentifying them as auctioneers that only shows an ignorance of their lore that can easily be looked up, and in intentional desire to not discuss the story by not doing so.
Jandria was the least significant, being a Priest Trainer in the game, but lot playing a larger role in the story beyond being one on the priests that would not abandon the Temple of Elune during the burning of Teldrassil.
Astarii Starseeker was also a Priest Trainer, but she played a part in a questline as far back as Classic where a Night Elf soul that had joined the Twilight’s Hammer sought forgiveness and salvation from Elune and was granted it, and in addition to that Astarii Starseeker lead the Priestesses of the Moon in the defense against the Horde in the War of the Thorns.
Denalan was perhaps one of the most interesting characters on Teldrassil, having been involved in unusual quests about how plant life grew on top of the tree, which back in Classic established a sense of mystery involving the giant tree, not just in investigating the corruption that affected it by researching the plant life on there, but also how plants from as far as the other side of the planet such as from the Swamp of Sorrows had come to grow on Teldrassil. Quests that survived through the Cataclysm revamp and helped flesh out Teldrassil’s questing experience.
Ferryn was previously only a character found in the Elegy and A Good War novels, and while notably Delaryn’s love, he was also responsible for organizing the efforts during the War of the Thorns that held the Horde back at the Falfarren River until Malfurion could arrive. Unfortunately Ferryn saw an opportunity to attack Saurfang and took it in hopes of ending the war there without Saurfang’s leadership, but Saurfang saw Ferryn’s attack and countered, killing Ferryn.
Anaris Windwood likewise was previously only a character found in the Elegy and A Good War novels, but was important in that she had been the leader that retook Silverwind Refuge from the Horde after the Alliance player had crippled the Horde’s hold there in the Ashenvale Cataclysm questing, being a rare instance where “You’ve done enough <class>, we’ll take care of the rest from here” style questing was actually followed up, even if it was only mentioned years later in a novel.
And Ilthalaine is the first character a Night Elf player meets when starting a new character on Teldrassil, which story wise is rather significant in sending the player on their first steps towards everything else they would accomplish in the lore.
