As a suggestion you could potentially add a 5th knight with the title Alfheim: The White Knight (totally get the nordic mythology references and highly approve by the way). The downside is while it is a cool sounding title and would be highly appropriate to have along side Nifelheim there is now obvious way to use a 5th knight. So I guess rather than a suggestion its more of an idea for possible toying with. Regardless of that I most likely will be posting up an app for playing an Intelligence Faction character here shortly just felt like adding my 2 cents worth on a potential addition for now.
