|The Brothers' War|
He became an apprentice to Urza once the latter managed to drag him away from his work at the Yotian laboratory by presenting him a self-made snake-toy. Many of Tawnos's creations inspired some of Urza's later designs, like the falcon engines and Urza's armor. Tawnos as an artificer was notable for having his creations inspired by living creatures and using nature's inventions in order to improve efficiency of his artifacts. Tawnos was also a trusted friend to Yotia's queen, Kayla bin-Kroog throughout many years preceding and succeeding the fall of Kroog. Tawnos also helped raise Harbin while Urza was away.
He accompanied Urza to Argoth, and survived the Sylex Blast sealed in his coffin. He remained there for 5 years until he was released by the ascended Urza. He returned to Kayla and related to her the events of the war's final battle.
Among notable Tawnos creations are a wand that protects small mechanical creatures from detection, a coffin (originally designed to trap Mishra indefinitely, rather than kill him), Clay Statue golems designed to fight against Ashnod's Transmogrants and a multitude of mechanical devices used and improved by Urza during the Brothers War.
