Literally, the Klingon word meaning "the bonding."
In a sometimes violent society such as the Klingon
Empire, orphans or those without a family or House are not uncommon.
The R'uustai, a ceremony of adoptive brotherhood,
takes place to cement ties between the non-related.
Both participants wear ceremonial vests and each use
a candle to light their own set of three large candles apiece as they
invoke the memory of their mothers by reciting "SoS jIH batlh
SoH" ("Mother[s] I [we] honor you").
According to the tradition, once the ceremony is
performed, they are now brothers, and their families are stronger
because of the union.
