The Dwemer; "Deep Elves", or "People of the Deep", more colloquially known as Dwarves. They disappeared without a trace because of Lord Kagrenac tampering with the Heart of Lorkhan, right? That's all I really know, and it's the only explanation I can think of. I don't know where they went, all I know is that there is one; one who left Tamriel like the rest of them, but did not go wherever the rest of them did. How do I know this?

I am him.

My name is Mzarec Rthangnchad. I am the only Dwemer in this world. Possibly the last anywhere. This is my tale.

A/N: I put if the 'human' tag on just in case, but I don't know if it is truly necessary considering that our protagonist is an elf, and not a human.
