Algar is a dwarf of middling age, formerly of Highhelm. He was a smithy, as many dwarves are, but had something of an odd streak in him. He found glory in the flames rather than in the steel, and would spend even idle hours near the smithy to feel the heat and revel in it. This wouldn't be particularly enough to have him exiled, as he is, so of course he could not have left well enough alone.
In the Iron Archives are many books, including one on beasts best left alone. He found the story of Apsu and Tiamat, as well as Dahak, and it seemed to light a fire within him. A rather literal fire. He hadn't brought a torch, nor any other object which could have damaged the tomes of the Archive, but from somewhere within himself he discovered flames welling up and begging to be released. Not thinking that it would actually result in real fire he did so. It did. Flames erupted from his body, burning not only the book he was reading but a number of other priceless tomes and ledgers. He swore he had not done it intentionally, but given the destruction and the witnesses who saw him and saw the fire with no other possible source, he was judged guilty of the wanton destruction of documents.
Having been exiled from his home, he didn't get very far and started working for Crink Twiddleton at Quarters and Bits. The other smiths don't think much of him, but he can make a living with horseshoes and iron kettles.
