'Klaven' is not a word.

Report: White supremacists set up Colorado chapter

'OLATHE (AP) - A Ku Klux Klan member from Indiana has said the white supremacist group has a chapter in this small western Colorado town, but city and county officials said they are skeptical.

Railton Loy, who says he is the international imperial wizard of a Klan group, told the Rocky Mountain News in Tuesday's editions that the Olathe chapter was formed about four years ago. He said he did not know the names of any of the members.

"It's just a little Klan klaven," he said.'

I think he meant Klavern:

klav·ern n.
A local organizational unit of the Ku Klux Klan.
