Howdy GitP!

In an upcoming game, I would like to play a cleric of a Lovecraftian god, however I have only read a book or two, and don't know any myself. I looked around wikipedia, however its write ups did exactly give me a comprehensive look at what there portfolios would be so I could write up their spheres (I'm one of those weird elitests who still play second edition). I was wondering if one you would be willing to provide me a brief explanation of a few, and what they represent. Once I have a starting point, I could read up on them and get the rest myself.

Thank you in advance!
