Name: Flynt Silverflame
Class, Race, Background: Dragonborn Paladin of Bahamut (Oath of Vengeance), Acolyte
Quote: "Let's unleash Hell"
Treasured Possession: Two chess pieces, one that represents his god and the other representing his "Little Brother."
Backstory: Like many dragonborn, the silver-scaled Flynt was born in the region of Tymanther to a militaristic mother and father. His closest friend was his twin brother Steel, a promising sorcerer who threatened to leave after a dispute with their parents. One evening, Steel told his brother to find his own path and Flynt never saw his brother again. After training as a paladin, Flynt attempted to save a pair of children - rescuing one but dying to save the other. After Bahamut brought him back to life, Flynt devoted his life to traveling the world, protecting the innocent and destroying evil in Bahamut's name. 

I love me some Nentir Vale (although I have not read this adventure)!

I have a tiefling character lying around who might fit the bill: https://ddb.ac/characters/27651746/B3tRZj

Name: Renewal

Class, Race, Background: Druid (Wildfire), Tiefling, Hermit

Quote: (Long pause)... "Fire brings agony, true, but also healing and rebirth. Just like life."

Treasured Possession: A letter, written in no known language, that was found wrapped in his blankets with him when the druids rescued him.

Backstory: Renewal never knew his true parents. He was raised by the Harken's Heart druids, who found him abandoned in the Harken Forest as an infant. He's been told that they were at first tempted to let him die, but their hearts were turned by his soft coos and gentle laughter. As he grew to adulthood, his affinity for fire magic frightened them, but he was never anything but true to their teachings and their mission of protecting the forest. Harken's Heart recently discovered that Renewal is somehow immune to the curse that keeps them trapped within the wood, and so they have sent him forth into the wider world, to be their eyes and ears. He is on his way back to the Harken Forest from Fallcrest along the King's Road when he enters the fray...

Name: Soakossh

Class, Race, Background: Sorcerer(Divine Soul), Yuan-ti, Acolyte

Quote: "Have you found salvation?  Now you have."

Treasured Possession:  The skull of the missionary who died for him.

Abridged Backstory: A priest of Avandra found their way to a yuan-ti enclave to try and redeem their mortal souls.  He was promptly eaten alive by the snake people.  As the priest died, he cried out to his god to save these wayward souls.  Soakossh believes by consuming the flesh of a holy man, the spark of divinity was awoken in him.  As all yuan-ti do, Soakossh wants to ascend and evolve, but he believes can do so by gathering worshipers in his name.  To this end, he travels, performing miracles and fighting for the oppressed.  Arrogant, self-centered, and devoid of empathy, Soakossh nonetheless believes it is more effective to gain acolytes through love than through fear.  He was starting with the small towns along the King's Road when he stumbled into the territory of the Iron Ciircle.

Class, Race, Background: Hill Dwarf Cleric of the Forge

Moradin had blessed him with his abilities, and Kairn vowed to give back while striving to become the greatest smith in the land. He began traveling, seeking out new techniques and metals when he first crossed paths with the Iron Circle. After learning about the mercenaries, he's decided to try to help out the resistance wherever he can.

To prove his worth he was sent on a vision quest, to fast for 3 days while traveling the woodlands, letting the Gods guide him. On the 3rd day, suffering from hunger and thirst, he saw a light among the trees. He followed the light to a small clearing in the midst of a thick forest. There he found the bones of humanoid holding a broken sword. He reached for the sword only to be attacked by a spirit. The battle was fierce and Valor was at the point of dying when he made his battle cry and struck the spirit. Valor fell to the ground and the spirit, screaming, dissipated. The forest was suddenly filled with golden light and a woman in armor stood before they dying Valor and she spoke, "Valhalla is not for you yet youngling. Go, take thy prize and return to thy people." With that Valor was healed. Amazed, Valor took up the broken sword and fell into a trance. While in the trance he saw a man he believed was his grandfather holding the broken sword Valor now possessed. Then he saw a circle of iron and war in the background. The scene changed and Valor saw a giant face of the God of War, staring at him. Valor awoke with a sense of urgency and a silver holy symbol of the war god hanging from his neck. Returning Valor met some merchants who told him the news of bandits in the land. Valor now rides to defend his homeland with the blessing of the War God.

Treasured Possession: Hand-carved flute and a lock of hair given by a lost love.
Backstory: An orphan, Tanisar had no family growing up, but he was always well-liked by those he met. He never stayed in one place for long, earning his keep by entertaining at inns and taverns. One day, he fell in love with a simple barmaid, and the two began making plans to spend a life together. However, she was killed when she stopped a thief from making off with the day's earnings one night.

Name: Kip Baker
Class, Race, Background: Conjuration Wizard, Variant Human w/ Magic Initiate (Sorcerer) feat & Guild Artisan (cook) background
Quote: "We can beat this... we just need the right ingredients!"
Treasured Possession: A well-seasoned iron skillet that belonged to his grandfather.
Backstory: Kip was born to a family of bakers who urged him to ignore his inborn magical gifts and pushed him to become a brilliant, well-trained chef. Then, as fate would have it, a chance encounter helping a mage led him to begin exploring the arcane arts and (to his parents' dismay) to become an adventurer. Oh, he plans to keep his skills sharp (even improved?) and be ready to open a famous restaurant when he's finished. But he's had a taste of adventure now, and has questions that need answering--and he's decided to scratch that itch while he can.

Name: Vutha

Class: Circle of Spores Druid - may multiclass into war cleric, ranger, or fighter to increase my ability to stay in melee

Race: Lizardfolk

Background: Folk Hero

Treasured Possesion: Spear made from the Otyugh he slew for his tribe

Quote: "Stop eating the dead? Why? It would waste the good meat. And they are delicious. Is this one of your strange softskin traditions? I will respect it then. Do they need the fingers? I could really use a snack." (Love including a quote, great idea)

Backstory: Vutha grew up deep in the swamps near the kings road. His people kept to themselves, killing those who entered the swamp but ignoring the outside world. Vutha trained under the shaman of the tribe, learning the ways of Semunya. He earned his name when he hid in a pool of black water for three days, stalking an Otyugh that had wandered too close to the village. He ambushed it and with the aid of Semunya and a few of his brethren, they slew the beast. Recently strange humans have been invading the swamp and killing his neighbors. Vutha has been sent to stop these humans and is venturing out of his swamp to find the murderers.
