I was flipping through my D&D books looking for a character to play in an upcoming campaign when I flipped to the warforged. Considering warforged are artificially created to wage war I thought to myself, why does a warforged always have to be built to resemble a human, they can be built to resemble other creatures and it wouldn't change how they played or their stats. So I ran the idea past the DM and he thought the same way, so presto this is whaat I came up with, since he wouldn't alloy me to play a wererat lol.
