Arc 5The Fall of Lordaeron
Medivh manipulated Thrall and Jaina while Arthas uncovered the curse on House Menethil and joined Baron Rivendare to defend Lordaeron. After Thrall and Sylvanas turned against the fortress, Medivh moved to seize Arthas, but Kel'Thuzad intervened and summoned Arthas to Andorhal.
- Medivh pushed Thrall to rule the Orcs through fear, while Jaina survived his dungeon test and was recruited to lead the Peace Dove.
- Thrall killed Orgrimmar, formed the Kor'kron, and began uniting the Orcs, as Medivh learned Kel'Thuzad was hiding in Andorhal.
- Arthas and Robbie reached Lordaeron and discovered the suffering of its people, King Terenas’s plans for the Orcs, and Uther’s effort to remove Baron Rivendare.
- Robbie entered Undercity and found the Runes of the Dead, which he and Arthas later combined with Holy Light runes to gain new powers.
- Robbie fought Uther at the palace, weakened him, and struck Missrael as she teleported Uther away.
- Arthas and Robbie joined Baron Rivendare at Blackmist Fortress, where Arthas trained against Orcs and received Holy Light's Vengeance.
- Thrall enlisted Saurfang and Sylvanas against Rivendare, but Arthas defeated Saurfang and Robbie turned the rangers’ arrows back on them.
- Medivh tried to capture Arthas for his bloodline, but Kel'Thuzad intervened, sent Thrall and Sylvanas away, and summoned Arthas to meet him in Andorhal.
