Here are the content notes for "Because You Have Made It So."
"Marriage: If you want something to last forever, you treat it differently. You shield it and protect it. You never abuse it. You don't expose it to the elements. You don't make it common or ordinary. If it ever becomes tarnished, you lovingly polish it until it gleams like new. It becomes special because you have made it so, and it grows more beautiful and precious as time goes by."
-- F. Burton Howard
Group marriage entails polyamory, which is one type of nonmonogamy. These relationships can take different shapes.
In Terramagne-America, the Mormons won the dispute about polygamy on the grounds of religious freedom, so it remains legal in Utah. However, the compromise was that the law had to apply to any combination of people, not just one man marrying several women. Polycules may travel to Utah for a wedding, and the marriage will be recognized (often grudgingly) in other states. The number of people choosing this option is fairly small, which keeps the conflict down to a dull roar.
In Terramagne-America, a foursquare refers to a polyfamily which has two sexual/romantic couples and some other connection between the cross-couples. In this case, the couples are Hefty/Roger and Fiddlesticks/Diamond; Hefty&Fiddlesticks are beat partners, while Roger&Diamond are queerplatonic friends. Another example occurs when two brothers marry two sisters.
Queerplatonic partners are called zucchini.
