Dongo is a cave dwarf blacksmith who apprenticed under Wabon. Despite constantly being harassed by his master, he became an excellent smith that crafted many of the rails, nails, and even the mine carts used in Wabon's long underground railway. Over time he developed an interest in forging weapons, even travelling to Stormfist during the Sacred Games for this purpose, despite being turned away. His interests brought him under constant lecturing from his master, who regarded weapon forging as anathema.
Eventually Wabon grew fed up and fired him, allowing Dongo to join the Imperial City Recapture Army as their blacksmith. He quickly became an accomplished blacksmith, despite his initial difficulty sharpening unusual weapons like whips and books. He was even asked by Mohsen to forge armor, but had to refuse due to a lack of knowledge in that area. During the war he got along well with Bergen and Sorensen, both fellow apprentices constantly badgered by their masters.
Following the Sun Rune War, he was recognized as a skilled smith, despite having to put up with constant browbeating from Wabon.
