I actually only have access to the SRD, but I've liked what I've heard about the elements in Eberron, so I figure I'll give this a go. I've been playing with this character concept for a little while, and thought it fit pretty nicely into the setup you have here without much fiddling. Then Bront suggested his paladin character above, and I thought the roleplaying possibilities inherent in putting Midian in the same party were pretty fun.
Midian Rightson, Druid 1:
Midian was supposed to be a paladin. Priam the Righteous, his grandfather, started the line. His was a tale of noble quests and brilliant wars fought in the name of goodness. Midian's father, Rolav Rightson, carried on the fine tradition. Rolav married fellow paladin Verita del Pristien, and together the pair spread good and law with their every breath and smote all evil they came across. Even Midian's older sister, Penance, has heard the calling.
It's not that Midian didn't try. He enrolled in the School of Chivalric Arts at the University of Wynarn. His way with animals helped him master riding. He showed some promise at archery. He studied his own lineage and that of all the important authority figures whose law he might be called to uphold. But each success was met with its own failure. Heavier armors dragged him down and turned him into a stumbling idiot. Try as he might, he could only get the feel for a handful of simple
weapons well enough to be effective with them in close combat. And, most importantly, no matter how hard he prayed and focused, he simply couldn't hear the call.
At least, not the call of the paladin.
In Midian's third year at university, a visiting professor and druid named Byless Delavert joined the faculty. Midian had intended to take the elf's botany class for some easy filler, but Byless proved a fascinating, charismatic instructor. Midian found himself signing on for animal husbandry with Byless the next session. A few weeks in, Byless pulled the young man aside after class. The way of the paladin would never be Midian's, he declared, but with Byless's help, the elf was certain Midian would make an exemplary druid.
It was far too late for Midian to change his course of study as far as the university was concerned. If he wanted his degree, it would have to be from the School of Chivalric Arts. So Midian continued, but Byless offered--and Midian accepted--private tutoring in the ways of the druid. He won his degree by the skin of his teeth and a lucky stab with a shortspear in his Advanced Sparring final. His stellar performance in his uncredited druid training, however, was Midian's true point of pride.
The family Rightson still hopes that one day their youngest member will be gifted with a celestial mount, that his gaze will know evil at a glance and his sword arm have the power to smite that evil. Midian is content to have befriended Talbot, a heavy horse who--like him--hadn't taken to the training of a full-fledged warrior. And he hopes that one day his kin will come to accept the valor of his own, less well-trod path.
