I think there was also some pdf document by someone on the net from the RM community which had insanties in it, as well as the mentioned books.

Found it. It was a "Sanity System" but for HARP. Was published by Allen Maher and can be found in the Guild Companion, can't remember the issue though. It can also be found in the Vaults on HARPHQ. The direct link ist this: http://www.harphq.com/free_downloads/Maher-HARPSanitySystem.pdf
