It was not only the Kingdom of Gilneas that underwent drastic upheaval; the Kingdom of Stromgarde did as well. After the Dwarves repaired the stone bridge connecting to the Arathi Highlands, the expedition hero Danath Trollbane led the elite expeditionary force and the Alliance Sixth Legion successfully into the Arathi Highlands.
Due to the Assassin League and SI:7 sealing off all information, the pitiful king of the Kingdom of Stromgarde, Galen Trollbane, knew nothing of what was happening in the south.
The trusted men he had sent to monitor the southern entrance to the Arathi Highlands were actually members of the Assassin League...
Those returning expeditionary soldiers also realized that, compared to Danath Trollbane, Galen Trollbane was utterly unworthy of being their king.
Furthermore, the nobles of the Kingdom of Stromgarde had been taken hostage one by one by the Assassin League and SI:7. Without Galen Trollbane knowing anything, Stromgarde threw open its gates and welcomed Danath Trollbane and his forces inside.
After returning to Stromgarde, before all its people, Danath Trollbane exposed Galen Trollbane's so-called filial deed of murdering his father and king. It turned out that the old king of the Kingdom of Stromgarde, Thoras Trollbane, had been killed by Galen Trollbane.
Thoras Trollbane had enjoyed the greatest prestige of any king in the history of the Kingdom of Stromgarde. Though he had grown muddleheaded in his later years, sending his main forces to Grand Marshal Garithos and Jaina, which caused the Kingdom of Stromgarde to decline from prosperity.
The enraged people of Stromgarde refused to recognize Galen Trollbane as their king, instead welcoming the expedition hero Danath Trollbane, a blood descendant of House Trollbane, as their regent.
When the news reached the Hillsbrad Foothills, it nearly made Fakurest, the besieged king of Alterac, laugh himself to death.
