Margaret Weis has acknowledged Terry Phillip's The Soulforge gamebook for Advanced Dungeons & Dragons as the inspiration for the novel.
[2] Brothers in Arms is a Dragonlance book, the second of the Raistlin Chronicles, written by Margaret Weis and Don Perrin.
Brothers in Arms begins where The Soulforge left off, after Raistlin Majere has passed the Test of High Sorcery.
Kitiara succeeds, and the orders are to go to the city of Hope's End, and find the hiding place of the Gold and Silver Dragon Eggs.
Meanwhile, the twins have joined the Army of the Baron Ivor, and are trained: Raistlin as a war mage by Master Horkin, Caramon as a warrior.
