A golem is a ritual-created being made of clay. They are very strong and not particularly bright. They are almost indestructible. Only the Cabal of Mu knows how to make them now, but the ritual was also known to Jewish Sorcerer-Rabbis who learnt it from Loyalist angels. The last of these Sorcerer-Rabbis was killed in the 16th Century, but there may be surviving golems, still obeying their Rabi masters' last commands.
