Subrace
From HGWiki
Subrace - A subrace is a feature of DND and particularly NWN. In the Persistent World - Higher Ground a player may modify their characters stats and appearance beyond the normal game content given that they have access to a Standard Subrace, Secret Subrace, Ultra-Rare Subrace, Beyond Ultra-Rare Subrace or Extremely Rare Subrace. These modifications happen post character creation and you are prompted at the docks when they are implemented, if you have made a typographical error with the subrace name or do not actually have access to the subrace in question you will receive an error message when the the subrace is activated.
One thing to note is that all 'Large' size characters will require one re-log to be implemented, prior to doing this you will not be able to wield large weapons one handed or be able to use huge weapons at all.
