First I must point you all towards your lack of information. On PS's original concept we, the players, could not have characters bend on doing evil alone. Mainly because they stated people would be busy attempting to stop an invasion of creeps and producing materials to aid on that quest. Oh wait. That was ignored a long time ago. Ha ha ha. How distractful of me.
Still, I think it foolish to create guilds with the purpose of being evil. It doesn't fit PS's setting (where things should have a normal, realistic course instead of sudden, demonic, mutant, dragon, vampire path.) I am really sorry that people continue applying alignments to PS. It is really sad to see people falling prey to the unoriginal task of choosing an alignment, instead of creating fluid, realistic characters, that may be considered evil as they interact with others who may consider their traits less moral.
This might sound strange from someone who owns a "Dark Empire." However, unlike other guilds, the Dark Empire is only out there to establish itself through whatever means it has. It doesn't do good, it doesn't do evil. It does what it has to do for itself. Why name it dark? Why name France, France? Most of us don't know it nowadays, and it really doesn't matter as it is just a name.
Our objective is to create a persistent world in a fantasy setting, in which every player will create his character and will be able to live, explore, and interact with maximum realism.
I am quite aware that even most GMs are not aware of how the RP setting should be enhanced. Probably it's because this is an alpha test, and we are tester before being roleplayers. However, we should try going the right way, even while having such a lack of direction from the GMs and the PS team. There are specks of information we can cling to, and we can always use logic.
