And to be clear, the Borak are not snails; they as a species look like this, and their ships (that could have been) look somewhat like these. (I suspect Jean was just using the "snail" idea as a hypothetical, and wasn't intending to tie it to the BSL.)
As Iron Domokun noted, the E-series modules are intended to be interim playtest packs, each useful mainly as a stepping stone towards what will hopefully one day be a formally-published module.
Indeed, this has already happened for one of the E-modules; while modules E2 (Triangulum Galaxy), E3 (Borak Star League) and E4 (Peladine Republic) remain playtest material, the now defunct Module E1 (Magellanic Cloud) has been officially superseded by the "full" Module C5.
