Ronin family names are rare, but they are not wholly unknown. They are most often created when the Emperor chooses to reward a ronin for an exceptional deed, such as Usagi helping to defeat the Bloodspeaker, Tsi creating a magnificent weapon for the Imperial house, or Yotsu rescuing the Emperor’s son. Usually, these families quickly gain the right to create a Minor Clan (such as Usagi becoming the Hare Clan) but on some occasions they continue as ronin families for many generations. Eventually such families either die out, become a Minor Clan, or get absorbed into another clan or family. For example, the Tsi eventually become the Oriole Clan and the Kaeru become a vassal family of the Ikoma. The Yotsu in the canonical L5R timeline have sworn fealty to the Seppun family and may be on their way to being absorbed by them.
A ronin family can also be created when a samurai family is officially disbanded but its members refuse to accept the judgment, clinging to their name and traditions while living as wave-men. The Akodo and the Usagi during the Clan War and Hidden Emperor eras are examples of this phenomenon, as are the Tsume in the Heroes of Rokugan era. Unless they can restore their reputation, these sorts of ronin families tend to die out within a couple of generations, both due to loss of faith among their members and enmity from clan samurai who consider their behavior improper.
Mechanically, a ronin PC who belongs to a ronin family must spend 5 Experience Points on Social Advantage: Ronin Family. This grants him the ronin family’s Trait bonus as well as social connections to the rest of the family— the GM may award a variety of bonuses and obligations in play based on such connections. Such characters still technically have Status of 0.0, but their name grants them a certain degree of respect from clan samurai that other ronin do not receive.
Generic Ronin
The ronin mechanics in the L5R 4th Edition RPG are designed to reflect the unfortunate reality of a wave-man’s life - namely, most ronin bands are only around for a short time, and are unable to develop more than one Technique. Even the rare ronin groups that manage to endure for a long time or gain prestigious support, such as the Legion of Two Thousand, are hard-pressed to establish the sort of infrastructure and long-term continuity required to maintain a full-fledged bushi school.
