Andorians frequently decorate with geodestones, which may indicate an abundance on their homeworld. The planet boasts the Andorian Academy of Art, said to be the finest school of its type.
Native lifeforms include the a horse-like animal called a 'zabathu;' the 'Andorian bull,' noted for stomping around when angry; and the 'Andorian amoeba,' which reproduces through symbiogenesis.
In the 26th century (or one possible version thereof), the Federation defeats the Sphere Builders at the Battle of Procyon V. One might suppose that in this timeline, Andor is destroyed or severely damaged by spatial anomalies, smilar to those found in the Delphic Expanse.
Andoria is a frozen world orbiting a white subgiant deeply coreward from the heart of the empire.

In Andoria’s cities and villages, every street is decked in imperial regalia, and the Andorian fleet is one of the deadliest tools in the Emperor’s war machine.
