Is this passage correctly structured and worded?

When the Elder Circle learned that Evendur’s fleet was moving toward Sapra, they hastily assembled the city’s forces and prepared to meet the enemy in battle on the sea. Stedd was still I unconscious, but Anton, Umara, and the other Thayans joined the Turmishan army that was going to engage Umberlee’s minions. Since the Elder Circle’s main responsibility was to protect and nurture the wild lands of Turmish, only Shinthala decided to directly participate in the battle, while the other two Chosen of Silvanus would lead a group of druids in providing magical aid to Sapra’s defenders.
