Monster Whisperer

My clients at my vet clinic have always called me an animal whisperer. I've never questioned it. Until I started hearing monsters too.

A man came in right at closing with a sick dog. The dog told me why he was sick and I was able to treat him. I had no idea his owner would kidnap me. I had no idea his owner had an entire dungeon of monsters he wanted me to treat. I've met a minotaur, a mysterious kraken, a phoenix, and this really massive spider.

I can hear them too. If monsters are real and I can talk to them, then what am I?
