Kalthars

Kalthars are a fictional species of humanoid aliens originating from the *Mass Effect* universe, developed by BioWare and published by Electronic Arts. First introduced in the 2007 video game *Mass Effect*, they are a highly advanced, amphibious civilization native to the planet Calyx, located in the Kethona system of the Andromeda Galaxy. Their society is structured around a rigid caste system, with individuals assigned roles based on genetic and societal criteria rather than personal choice.

Physically, Kalthars possess a distinct appearance marked by elongated limbs, webbed hands and feet, and a smooth, pale-blue or grayish skin. Their eyes are large and reflective, often glowing faintly in low light, and they breathe through gills located on the sides of their necks, allowing them to survive underwater. Their culture places significant emphasis on discipline, order, and collective survival, with a strong military tradition and a deep reverence for their ancient history and traditions.

Kalthars play a minor but notable role in the *Mass Effect* trilogy, primarily serving as a neutral faction with whom the player character, Commander Shepard, may interact. They are depicted as a peaceful but militarily formidable species, often engaged in conflicts with other Andromedan civilizations. Their society is governed by the Council of Elders, a ruling body composed of the most respected and knowledgeable individuals within their caste system. Despite their advanced technology, Kalthars remain largely isolated from the rest of the galaxy, preferring to focus on their own survival and expansion within Andromeda.

In the games, Kalthars are encountered as allies, mercenaries, or adversaries, depending on the player’s choices and alliances. Their unique biology and cultural values make them a fascinating study in contrast to the more familiar species of the Milky Way Galaxy, such as humans, Turians, or Quarians. Their role in the *Mass Effect* narrative highlights themes of cultural preservation, adaptation, and the challenges of coexistence in a galaxy filled with diverse civilizations.
