Gethen

Gethen, also known as "The Left Hand of Darkness," is a fictional planet from Ursula K. Le Guin's science fiction novel. It features a unique environment with a cold, icy climate and an ambiguous atmosphere. The planet’s most remarkable feature is its inhabitants—species that are ambisexual, meaning they can change sex and do not have fixed genders. This fluidity influences their society, culture, and communication. Gethen explores themes of gender, identity, and social structure, challenging human assumptions about gender roles and highlighting the diversity of possible ways societies can function.
