The Amarrat Armada (Arken Freeth and the Adventure of the Neanderthals)

The Amarrat army continues its march across the northern land route to attack Lanth. But Arken Freeth has been critically wounded by his encounter with a deadly Tant and may not survive to lead the Nanders to war. Meanwhile, the Amarrat armada is crossing the Circle Sea to rendezvous with their army at the River Zash.
Zuul, the Amarrat king has equipped Yolanta, king of the Tookans, with a fleet of twenty fighting ships, and he is leading the Amarrat armada across the Circle Sea. Yet Yolanta is plagued by doubts about his loyalty to Zuul after he invaded Yolanta's mind.
Lanth is frantically preparing to defend itself as Arken’s friend, Asher, sails to the Nander Water Cave. He is accompanied by his mother, the Queen of Tolaria, who plans to read the Necklace of Tol in hopes of divining a strategy to defeat the Amarrats.
The collision of these forces is inevitable. But who will win the battle at sea against the Amarrat Armada?
