Well, I've provided a list of magic types to pick from in the OP and I've described what some limitations are, so I don't really get what you're asking.

I also think because you're a dwarf warlock, your magic would probably be more damage-oriented rather then somehow like healing or team morale boosting.

And thanks for those links man, although if asked about it I'd have to tweak them so they fit a non-statistical RP setting rather then a statistical D&D setting.

Also, why hasn't anybody posted yet? Are you still comtemplating what to post or do you not know where to start?
