My name is Ocellus, and I am a changeling- an Infiltrator. I was bred and raised to deceive other creatures by changing my shape and appearance to resemble theirs, to absorb love and other positive emotions and bring the resultant energy back to my hive for our continued survival. For thousands of years my kind existed in secret amongst the other species of Equus, forced by fear to hide our existence lest we be seen as dangerous parasites.

Then came the ill-fated invasion of Canterlot by Chrysalis and her hive, which exposed the existence of changelings to all in the worst way possible.

My hive, and several others, chose then to reveal themselves to the governments of Equus, in hopes that we could disperse fears about our kind and prove that we were not inherently dangerous. Many of the hive's members were given freedom to go abroad as ambassadors of a sort, to show that we could contribute to a society as ourselves.

With my medical background and my abilities as an emotivore, I chose to pursue a career in psychiatry, to help those affected by trauma or other emotional issues more directly than others could. And I also chose to go to a place where few other changelings had dared before the Canterlot invasion- Earth, home of humanity, a species at once alien yet so much like the ones we share Equus with.

Through hard work, perseverance and a desire to help others, I have built a good reputation here. Hundreds of patients of many species have entered my office for help from my unique methodology, as I literally devour the pain they feel from a traumatic event, letting them more easily come to terms with it. I take pride in what I do, and I feel that I've made a positive difference in the worlds.

Today feels as though it'll be like any other... until two patients whose pain is a bit closer to home than I'd like make an appearance.
