A Scientist in Peril

A Princess on a Peaceful Mission
Scientific purpose
Dejah Thoris travels with an expedition studying air currents and atmospheric density. Her work serves not only Helium but the fragile systems sustaining life across Barsoom.
Capture by the Tharks
The peaceful party is attacked before its purpose can prevent violence. Dejah Thoris survives as a captive, carrying both her political identity and the vulnerability of a lone representative among hostile warriors.
An Appeal for Peace

A Voice Against Custom
A proposal for cooperation
Dejah Thoris tells the council that red and green peoples could cooperate to preserve Barsoom. Her argument names the Tharks’ lack of homes and affection as consequences of their communal order, not proof that change is impossible.
A moment of possibility
Tars Tarkas appears moved, suggesting that the appeal reaches a buried capacity for compassion. The moment collapses when a young warrior attacks her, showing how custom and violence police the community.
Escape and Recapture

Freedom at a Terrible Price
Flight with allies
Dejah Thoris escapes with Carter and Sola, taking the difficult route toward a distant waterway. The plan depends on secrecy and on the companions’ willingness to risk pursuit.
Carter stays behind
When the Tharks close in, Dejah Thoris refuses to leave Carter to die alone. He forces her to flee with Sola, and she is later captured again, while Carter is carried into Warhoon captivity.
A Marriage as Bargain

The Cost of Saving Helium
A political pledge
Dejah Thoris promises to marry Sab Than because she believes the agreement can end the siege of Helium. Her decision protects her people while surrendering her own preferred future.
Custom closes the choice
She tells Carter that a promise has binding force before the later ceremony takes place. Even when she loves him, political obligation and Martian marriage customs restrict what she may accept.
The Princess Returns

A Political and Personal Restoration
Released from the bargain
Carter’s intervention and the collapse of Zodangan power remove the immediate threat of forced marriage. Dejah Thoris returns to Helium, where her family and people welcome her.
Choosing a shared future
With the crisis over, she accepts Carter’s proposal, making their union a decision rather than a political instrument. Her return restores her public role while resolving the personal conflict that captivity created.
