Satsuei Clan

The Satsuei Clan is a former nomadic clan, yet has officially established roots in Uzushiogakure.

Background
This clan was once a nomadic clan, traveling around the world and visiting many places, however, it's population eventually grew too large for that, so they joined the recently set-up Uzushiogakure.

Kekkei Genkai
The Satsuei Clan possesses a unique kekkei genkai: all members of this clan are born with a body made of stone. As this is not a technique, instead a biological feature, it does not consume chakra and cannot be deactivated. This greatly enhances their strength and durability, however, it does make them slow and sluggish. Some very skilled members become skilled enough with the kekkei genkai that they can change the shape of the stone, such as turning their arms into blades.

Hybrids
Those who have one parent of this clan and one not, they receive a decapriated form of this kekkei genkai: they can activate it and deactivate it, however, it does consume chakra when they use it. The less Satsuei blood they have, the more chakra it consumes, and the harder it is to maintain it. Those who have less than one-eighth Satsuei blood cannot control the shape of the stone, and those who are one-sixty-fourth Satsuei or less cannot use the Kekkei Genkai at all.
