"The relationship system can only work in two way, starting out wise.
A) Player on player action - two consenting players agree to form a bond, doing an awakening system type thing. We would set guidelines and rules, but thats how it would start.
B) Players on NPC action- once a player gets to a certain level, enough time passes, or whatever requirements we dictate is fulfilled we can set up an NPC system for players to bond with.

After a player forms a bond with whoever, we would need a child system. Obviously the child would assist in fighting and story telling, but we would need rules."

Those were Dabombjk's words but as things are I agree with it. Obviously it isn't something we have to worry about immediately, but the child aging may be a complication...that being said there are many possibilities.
