Answering for my Draenei Shaman, Thuum, who I am pretty sure is going to be my new main in Shadowlands. Just don’t wanna switch characters on the forums so maybe I can one day post links 
Born after the rise of the Horde and the genocide of the Draenei, Thuum is a younger Draenei for sure. He never knew his real parents, and indeed no one seems to, not even his adoptive mother, a kindly old Broken Draenei woman. She found him while foraging in the swamps, swaddled and crying.
Growing up in Zangarmarsh, he developed a fondness for nature and the wilds. He had a pretty quaint and simple life, though not always easy. Being the uncorrupted son of a Krokul woman got him teased a fair bit, as the draenei could still be intolerant in those days of their afflicted brethren. And so from an early age, Thuum liked to fight and always wanted to ensure he was strong enough to defend his mother’s honor, much to her vexation it should be said, for she was a very kindly woman who abhorred violence and had a strong sense of herself, and certainly wasn’t overly bothered by the words of teasing children. A former Rangari who now worked as a scholar trying to study and hopefully one day cure the Lost Ones, Thuum’s mother believed in the value of all life, and instilled this in her son. This lead Thuum to have a fondness for all manners of creatures, and peoples. As a young boy, he became best friends with a Sporeling.
When Nobundo began looking for students, he found Thuum among them. Early into his studies, by now a young teenager, Thuum moved to Nagrand to live in Telaar and learn shamanism. He made pilgrimages to the Throne of the Elements to learn from the Furies themselves, as many shaman then did. His strongest elements were earth and fire, for his stubbornness and temper, according to his teachers, only half-jokingly.
And so he lived in Outland, training, learning, getting into whacky adventures I haven’t yet fully imagined. Content to be a shaman and tied to the lands of Draenor, he was not present when the Draenei took the Exodar and crashed it on Azeroth. However, during the Burning Crusade, he met the Alliance when they came to Telaar and became fast friends with many of them, especially the Dwarves and their ale. He came to Azeroth during the Shattered Sun Offensive, and from there decided to stay and do his part to protect the land and its people. Draenor was his home, and would always have a place in his heart, but he felt an instant connection and love for Azeroth from almost the instant his hooves touched down.
A member of the Earthen Ring, he has pitched in during many conflicts. Though a powerful shaman, especially for his age, he lacks ability when it comes to healing and spirituality. Furthermore, his boisterous personality, hot head, and wanderer’s spirit have made him, probably, the least dependable shaman in the entire Ring, so he has never really ascended into the ranks in any meaningful way. One of Thuum’s teachers said of him, “Thuum connects with the elements so well because he might as well be one of them. He’s as proud as fire, capricious as wind, as inconsistent as water, and as immovable as earth.” Another has said, “He is more a force of nature than a man. Coming and going as he pleases. Sometimes no one hears from him for months and then he turns up again. He would have been kicked from the Ring long ago, if not for two things: his sheer talent, and the fact that if he gives you his word he will do something - and getting his word is no easy task mind because the lad won’t commit to anything - he will do it.”
Desiring to always be strong, Thuum eats like a horse and trains heavily, both in shamanistic magic and combat. Even as a boy, his mother would have to yell at him to go to bed because she would hear him grunting out push-ups late into the night. During the Legion campaign, the Earthen Ring sent him to assist in Highmountain and there he became fast friends with the Stonedark Drogbar. To this day, he still fist-bumps people and, if he really likes them, calls them “brul.”
On the whole, Thuum might appear at first glance to be shallow. He laughs at burps and farts, chews with his mouth open, doesn’t seem to know how to moderate the volume levels of his voice, loves showing off his muscles, and seems to be incredibly proud and conceited. But he is also very kind and empathetic. His boasting is never done at anyone else’s expense. He has deep emotions and feels them strongly - perhaps too strongly. Kind of a big, dumb, himbo but who has a heart of gold.
Presently, after Cataclysm and MoP and BfA, Thuum’s patience has worn out with the Horde. Thuum has always been an incredibly tolerant person, and indeed has had connections with the Mag’har of Outland from his days at the Throne of the Elements and such. As a member of the Earthen Ring, he looks up to people like Thrall and Muln. But the Horde’s actions have been a lot, even for someone like Thuun. He’s not super bloodthirsty toward them or anything, and he deep down has hope they can come back from where they are (especially with THRALL on the Council - he’s a big Thrall fanboy). But that being said, when it comes to Horde aggression, he’s also not f***ing around anymore, either.
