Repeating myself, but doing so to provide an alias with full build. Because I do enjoy the build process.
A character concept: briefly explain who they are and what they bring to the party.
Droreck is a young, emotional, lava gnome, looking for new experiences and unusual opportunities. His sub-species is infamously hot-headed and ready to take insult. I also see them as more emotionally fluid, flowing from one emotional state to another with little provocation and less inertia. They have a reputation for angry responses because such tend to be more widely visible and memorable than acts of kindness. Especially with the entire sub-species having the pyromaniac racial trait. Anger can be quite visible, and destructive.
Droreck is a blast sorcerer, built to (eventually) help clear out groups of bad guys. Especially ones focused on cold . . ..
Backstory: A brief overview of your character's history, showing what motivates them.
Droreck grew up in the underdark lava gnomish village of Chlachan Glòrmho, which lies below the Southern Range of the World's Edge Mountains, adjacent to the magma stores which feed Mount Kaltafarr.
The citizens of Chlachan Glòrmhor depend heavily upon magic to protect their homes from the destructive properties of magma, but they also use it as a never-ending supply of energy. Their smithies and forges turn out some truly amazing work, most of which never reaches the surface, so very few citizens of Taldor know the village exists. This tribe is almost always at war with the Gouged Eye orcs, fighting from below while the Taldorian army fights them from above.
Droreck had a wonderful childhood: learning, exploring, and developing his innate magical abilities. As he reached the age of majority, though Droreck found himself falling into predictable patterns, found himself putting up with maintaining his known experiences instead of seeking out new ones. He decided to go out into the world and learn more, see more, do more, to ensure that he would live the long life he deserves. So, effectively, he is fleeing The Bleaching. He hasn't begun fading, but that hasn't kept him from being afraid of doing so.
Why Heldren: Why is your character in the small town of Heldren in southern Taldor?
Geography. As he comes out from under the Southern Range, the Taldorans he meets generally identify the metropolis of Oppara as a place where he will find all kinds of new things to see and do. Getting to the best road to Oppara requires that he go (at least very close to) Heldren. Having him go through it is a simple enough case.
A little crunch: This should at minimum be a race/class/archetype combo. I don't need full crunch at this time, but if that's your thing go wild.
Race: Lava Gnome
Class: Sorcerer (no archetype) with Elemental Fire bloodline.

Sidenote: I'm using online translation to Gaelic to provide simple names that aren't immediately obvious as that simple.
