when you pledge for a specific power and later you decide to leave this power after you reach high rank (5) do you keep the special weapon-equipment you were given by the specific power? can you sell it and buy it again ? do you have to buy it from the system that the specific power has in control or can you buy it from shinrarta dezhra?
I believe that you have to gain rank 3 to get access to the module. If you leave the power, you can't buy another on that powers modules. Players store modules, in cheap ships, to always have access to them. Once a module is brought, it is yours forever, as long as you re-buy or own the said ship, it was brought for.
