Blue Light monasteries were the local headquarters for the Order of the Blue Light on the Sa'ari homeworld of T'lessia. Each of the one hundred and six Sa'ari republics had at least one, located in their capital cities, however other, smaller posts, called chapter houses, were often set up in towns and villages within the larger nations, such as Tal'adin or Hiltone. The largest monastery, which served as the Order's central headquarters, was located in Tal'adin City along with the Foruma of the Lawyteret.
