The Frozen Throne: the expansion that finished Arthas's story
Naga, blood elves and a race to Icecrown. How Warcraft III's expansion turned a great campaign into a complete saga.
A year after Reign of Chaos, Blizzard released The Frozen Throne (2003). It could easily have been a handful of new units and maps, the kind of modest expansion that strategy games often received at the time. Instead, it delivered some of the most memorable missions in the series, introduced characters who would shape World of Warcraft for decades and closed the story of Arthas in spectacular fashion.
More than an expansion, The Frozen Throne is the second half of the story that Reign of Chaos started. This is a look back at what it added, how it told its story and why it still matters.
Where we left off
At the end of Reign of Chaos, the Burning Legion had been defeated at Mount Hyjal. Humans, orcs and night elves had fought side by side. But not everything was resolved:
- Arthas, now a death knight, served the Lich King, whose spirit was trapped in a block of ice — the Frozen Throne — atop the glacier of Icecrown in Northrend.
- Illidan Stormrage, freed by Arthas and then banished by the night elves, was at large, with powerful new abilities.
- Sylvanas Windrunner, the high elf ranger general killed by Arthas, had been raised as a banshee and bound to the Scourge.
- The high elves, decimated by the Scourge’s attack on their homeland, were scattered and leaderless.
The Frozen Throne picks up all these threads.
Three campaigns, one destination
The expansion is told through three main campaigns, plus a bonus one.
Sentinels: Terror of the Tides
Maiev Shadowsong, Illidan’s former jailer, hunts him down across the seas. Illidan has allied with the naga, ancient serpentine beings who appear in the story for the first time. Maiev’s pursuit is relentless, and her obsession raises questions about justice and vengeance.
The campaign introduces new night elf units and heroes, and features some of the most varied mission designs in the game, including naval sections and stealth objectives.
Alliance: Curse of the Blood Elves
Prince Kael’thas Sunstrider leads the survivors of his people. Now calling themselves blood elves, in memory of their fallen, they serve under an Alliance commander who despises them. Their need for magic grows desperate.
When the blood elves are betrayed and imprisoned, Kael’thas makes a fateful alliance with Illidan and the naga. It’s a story of desperation and the price of survival — and it sets up the blood elves’ future role in Warcraft.
Scourge: Legacy of the Damned
The Lich King’s power is fading, and he calls Arthas back to Northrend to defend the Frozen Throne. Meanwhile, in Lordaeron, Arthas’s grip on the undead weakens.
Sylvanas seizes the moment, breaks free of the Scourge and forms the Forsaken, undead who have regained their free will. She wages war against both the Scourge and the demons who seek to control the region.
Arthas, weakened, must race across Northrend, fighting through the underground kingdom of Azjol-Nerub and battling Illidan’s forces, who are also heading for the Frozen Throne.
Arthas versus Illidan
All three campaigns converge on the same place: the glacier of Icecrown and the throne at its peak.
The final confrontation between Arthas and Illidan is one of the great moments in Blizzard’s history. Two fallen heroes, each corrupted by their pursuit of power, meet before the throne. What follows changes Arthas forever — and its ending leads directly to Wrath of the Lich King, five years later.
Without spoiling the details for newcomers, it’s enough to say that the expansion’s final cinematic is one of the most iconic in gaming.
The orc bonus campaign
As a bonus, The Frozen Throne included The Founding of Durotar, a campaign starring Rexxar, a half-orc beastmaster, alongside his bear companion.
It plays almost like an action RPG: you control a small party of heroes, accept quests from characters, explore an open map, visit shops and gain experience. There are side quests, secrets and plenty of humour.
The campaign tells the story of the orcs settling in Durotar, their new homeland in Kalimdor, and their conflict with human forces led by an admiral with a grudge. It was an early glimpse of what Blizzard was about to do with World of Warcraft the following year — and a fascinating experiment in genre blending.
New units, new strategies
Each race received new units and heroes:
- New heroes for each race, expanding strategic options.
- New units filling gaps in each army.
- Neutral heroes that could be hired from taverns, such as the Pandaren Brewmaster and the Naga Sea Witch.
- Shops and new neutral buildings on the map.
These additions made multiplayer faster and more varied. The Frozen Throne became the definitive version of Warcraft III for competitive play — and for the custom maps we covered in From map editor to the birth of a genre. Most of the famous custom maps, including DotA Allstars, were built for The Frozen Throne.
Storytelling and tone
The Frozen Throne is darker and more personal than Reign of Chaos. Its characters are driven by obsession, betrayal and the desire for power:
- Maiev’s pursuit of Illidan becomes a question of whether justice can turn into vengeance.
- Kael’thas’s choices raise the question of how far a people will go to survive.
- Sylvanas’s revolt is a story of reclaimed freedom — and of what she becomes.
- Arthas’s journey is the final stage of his fall.
It’s a story without clear heroes, and that’s part of its strength.
Why it still matters
Without The Frozen Throne there’s:
- No Sylvanas as a faction leader.
- No Forsaken in the Horde.
- No blood elves as a playable race.
- No Illidan as a major figure in Outland, as seen in The Burning Crusade.
- No Lich King waiting in Northrend for Wrath of the Lich King.
Almost every major storyline of early World of Warcraft traces back to this expansion. Our overview of twenty years of World of Warcraft expansions shows how these threads were picked up.
