Reunited with Arhilka and his family, Rakvir Stagarnik marries Arhilka, becoming Duyar of Kerkrand. He defeats the Magd armies on Karizhian soil and subsequently unmasks the traitors at the court of the Zgar. Allied with neighbouring realms also invaded by the Magd, he attacks their main northern fortress successfully with a rain of fire. Asked to command the Karizhian army, he attacks the Magd from the west, destroying their main army at the "Pass of the Warriors", but only after his allies' armies have been defeated by the Magd. As he attacks their last fortress in their capital, an immense lightning bolt strikes the fortress and kills many of the remaining enemy.
The fourth volume in the epic "Through Fire", "Magdarg: the Judgement of Subrid", is set in a distant planet, not too dissimilar from our own. Richard Hernaman Allen, a former Commissioner of HM Customs & Excise, wrote "Through Fire" over a period of thirty years.
