Rugen was the architect of Penari's Maze, which he considered the finest work he had ever performed. The architect cut off his own little finger to lay under the center stone, saying 'Blood and bone bind', and told people that he intended to be buried within it. An architect, in Tai-tastigon is a member of an essentially religious order, which has a sanctuary in the Temple District. In Penari's defense, he believed the architect when he said, in the argument, that he knew every turn of the Maze, and thus wouldn't need the plans to get out.
