Keras

Keras was the oldest of the People of M7G-677 and a village elder. He had several children located in other villages. When Maj. Sheppard's team arrived on M7G-677 he was on the eve of his 26th birthday and was about to take his own life as per the customs of his people to protect the others from the [{Wraith]]. When it was discovered that there was an Electromagnetic field protecting the villages of the planet, Maj. John Sheppard and his team convinced the people not to follow this tradition any longer, allowing Keras to continue life. {[Cite|ATL|Childhood's End}}
