The name of the Seventh Circle was inspired by Dante's Inferno. In the literary work, the Seventh circle of Hell is reserved for those whose sins were of a violent nature. The Natural Laws ban excessive modification to ships, as modification just like fanon designs can very easily get out of hand. The amount of modification done on Seventh Circle and Charon's Ferry is only permitted on the basis of the precedent set for Firespray-31 by Jango and Boba Fett's Slave I.
