Let's try to keep a standard format, like this:
Member #1 (possibly the leader): name, culture, class, age, background information, brief description. Role during Journeys.
Member #2: name, culture, class, age, background information, brief description. Role during Journeys.
Member #3: name, culture, class, age, background information, brief description. Role during Journeys.
I'll start with mine!
FELLOWSHIP OF THE SILVER HEART
Reinald Silverheart: Man of the Lake Scholar, currently 23 years old. Offspring of one of the richest merchant princes of Esgaroth, the Silverheart family, he acts as the group's spokesman and enterpreneur. He has a gift for tongues and dabbles in ancient, often lost (and forbidden) lore: he recently learned the ability to speak with the dead from Valderic (Rhovanion Guide), and his fascination with the dark arts is growing deeper. Unknowingly to him, he's the descendant of a bastard son of Girion and somewhere in his heart he feels he's destined to great things, maybe to the throne itself... but this may also bring a dark side out of him. Role during Journeys: Explorer.
Beran, the Crow: Woodman of Wuduseld, Warrior/Treasure Hunter, currently 19 years old. His father played a part in the disappearance of Ingomer's son, Ingold, who will later become Mogdred, the Lord of Tyrant Hill: Beran was also a childhood friend of Ingold himself. He inherited his (now deceased) father's blame and became an exile. A quiet man, a gifted archer and a hunter, he soon becomes a trusted agent of Radagast and a love interest of Banna (Wilderland Adventures), but he falls in love (unrequited) with the elf maiden Galia (also from Wilderland Adventures). Role during Journeys: Lookout.
Endimion, Swiftfoot: Dùnedain Wanderer, currently 21 years old. A Ranger trainee sent east of the Misty Mountains to act as the eyes and ears of the Rangers of the North, and ultimately of Elrond Halfelven. His mentor and master is Dirhael, Aragorn's grandfather from mother's side, who besides teaching him to fight and the ways of the wild, also acts as a fatherly figure for him since he's an orphan. He has frequent, prophetic dreams about the Werewolf and the Darkening of Mirkwood. He starts out as an impulsive youngster, becoming wiser and wiser as destiny calls for him. He and Galia (from Wilderland Adventures) share a romantic relationship, which brought tension with his comrade Beran who is also in love with Galia. Role during Journeys: Guide.
Gròr the Smith: Dwarf of the Lonely Mountain, Slayer, currently 43 years old. The son of a dwarf merchant slaughtered by orcs on the journey to Erebor after the death of Smaug, and a gifted smith. He's one of the dwarves who get lost in the Marshes during the Marsh Bell adventure, but he is separated from the group and gets lost in Mirkwood for months. Thanks to his incredible toughness and force of will he re-emerges on the other side of the forest, rescued by Bofri son of Bofur, barely alive and more a wild beast than a person. He seems to have discovered the Old Forest Road during his wanderings, but he can't recall almost anything of it because of the horrors he has seen. Role during Journeys: Hunter.
