At the end of The Saga Stone, you’ll have to decide whether to exile Eadwyn, or let Geadric look after her. Despite the implication, there are no future consequences for your decision. Geadric will still pledge an alliance with you regardless of the choice you make.
“Let her be exiled.”
Eivor states that Eadwyn should be healed and dressed in rags, then sent out onto the heath in exile. Eadwyn swears vengeance, but this will amount to nothing.
“Let Geadric look after her.”
Eivor states that Eadwyn fought with honor and purpose, and that she deserves to be treated well in Geadric’s care. Geadric accepts this, so long as Eadwyn renounces her friendship with King Aelfred, to which she agrees.
