Visiting the Crystal Empire for the first time, you see crystal ponies all around you, doing some sort of work. One of the ponies, who sweeps the streets, occasionally glances at you from time to time. Eventually, you approach her.

The mare looks at you, grinning, holding the sweeper in her mouth. She takes it out so she can speak

"Welcome to the Crystal Empire! I very much hope you enjoy your stay."

Interestingly, she doesn't put the sweeper back in her mouth. It seems she wants to have a conversation.
