Physically, they are of medium to small build, with a height that rarely exceeds 4 feet, but with a not insignificant weight that can reach up to about 50 kg. Given the great variety of shades and bizarre arrangement of colors on their bodies, it is not easy to list all the colors in their livery and place them in the correct position. Generally, gold is present on the hood crest, while vermilion red entirely covers the throat, chest, and hips. On the lower part of the nape, there is often an orange covering with black streaks. Their tail is very long, strongly yellowishwhite in color, and finely spotted with black. In contrast, females have a brownish-brown color with a considerably shorter tail. They don't have wings and instead have fleshy, featherless legs (from the knee down) and arms (from the elbow down), both dark or brown and four-toed. Their chicks are born ovoviviparous, meaning they hatch within the mother's body, and families usually never have more than 3 or 4 chicks throughout their lives.

Grouse people once were a scattered kingdom, with cities all headed by a king, and are known among eastern Anthros for their developed techniques and technology for farming in very difficult, snow-covered, and often freezing areas. In fact, they quickly developed innovative techniques to exploit their regions' geothermal energy and store it in warehouses where they could farm necessary food. But they are also renowned for their aggressiveness, both in combat and their approach to life. The daring and battle frenzy that often engulfs this quiet and herbivorous people's youngsters due to periodic sexual needs has often given rise to feuds and struggles. Hence, their need to create a non-violent culture based on sports competitions, acrobatic fights, and martial skill shows, for which the Zantist advent was crucial. Their annexation to Kibaya was far from peaceful and fast.

A distinctive trait of Grouse people's culture is their awe, in some cases even rejection, of magic, set aside for the benefit of science and technological innovation. According to some historians, Grouses "don't much like spellcasters because they would steal souls and tamper with minds." However, it is rumored that some of them are fond of elemental spells, as that school of magic suits their culture well.

They speak the Aevar language, a subtle and melodious language able to make even a dull and narrow text harmonious and poetic (perhaps a Spanish gibberish).

Religiously they are mostly lay followers of Zantist asceticism, practicing meditation and self spiritual research, but here and there still thrive some cults of Ayrus (deity of prophecies and time), Caamiran (deity of cities and law), Kalaukeke (deity of storms and competitions), Ekoari (deity of science and commerce) and Najan (deity of agriculture and community).

Their ancestral princes were V'dovuška and Reinèkè, who taught their race the importance of fighting and of strength appearance. While it is unlikely that one can survive a war against stronger and more skilled predatory races, that doesn't mean that one cannot put their opponent in fear and/or insecure conditions. This is true both on a physical struggle level and in everyday life. As proof of this strength, Reinèkè insists on the need for females to stay indoors to raise chicks and teach them the fundamentals of strength that, first of all, must be inner, but also outer.

Taking inspiration from the flying lanterns used by mice for holidays and celebrations, Grouse people have improved the flight system of balloons by inventing a first rudimentary hot-air balloon called tanii-shung. These are activated using gems enchanted with elemental fire, and small directional wind thrust spells for steering.
