They'd have to put up with Bowie, though, and that would be too much, for many people.
Bowie's not such a bad guy once you get to know him, and if you meet his high standards, and if you can tolerate his frequent cursing, and his quick temper, and his unpredictable behaviour, and his lechery, and his alcoholism, and his demonic interior, and his all around roguery.
Not to mention that you'd always be subservient to the guild founders. Realms, at least, hold the prospect of turnover, change, renewal, decay, being conquered, conquering others, etc. Guilds tend to get stale because there's no way to actually oust those at the top out of their positions. That's why guilds are so poor at making that kind of power structure. They require willing subservience, just like religions. So few people are willing to play along with that, except where required, such as in realms.
That is unless you suppose realms are the end all be all of power. What happens if the Aristocracy inverts that? Then whoever rules the most powerful Great House could rule more than one realm and issue titles and land as they see fit.
Royal houses. Which were actual families, actually related by actual blood.
Not just loose coalitions of nobles who were working toward some common purpose.
True, but only so far as the characters in the Great House do or do not marry each other (or their family members). This past few months have seen some high profile weddings, isn't that part of the purpose of the Great Houses? Maybe everyone should start thinking of their characters as members of a
family and start aiming to connect their family with others.
On that note, Bowie is single and eligible! Any women crazy enough to share his bed and his name? Maybe we should host the first ever Dwilight version of
The Bachelor?
