Echo culture.
[Seeing an Echo out of their shell is considered to be a very vulnerable position, they mimic the person they're exposing themselves to or crack their shell with holes large enough to let their wings uncurl and expand. The patterns and texture are only for selective people to examine and memorize and it is considered a very big step into deeply trusting a person. No one should be allowed to touch their wings unless they are one the Echo seeks for romantic interest.]
