All Enlisted ranks are non-negotiable, there are no special rank u requests, so on and so forth.
Commissioned officer ranks are as follows:
Lieutenant (Crew)
Vice-Captain
Captain ( currently Ferrer)
Officers ranks do not proceed any further due to the fact that gaia online already presets guild masters to the rank of Captain, and nothing can be done to change it. Thus no other ranks. (Note: yes i am very well aware of the fact that theres a multitude of other rates and ranks but i chose not to include them for very obvious reasons)
