My worldbuilding species

[Laterra]

They are covered in short, soft two-tone fur, have large hands, large ears, and three pairs of eyes, and have unusual patterns on their bodies.
They have genitals, but they don't have the ability to reproduce, and their natural life expectancy is infinite.

They were suppressed by other species because they could not use magic.

They had high technology, but they went extinct in a very distant era.
However, facilities and objects made with their technology are preserved up to the present age, and it is possible that their bodies and minds can be restored by them.
