Looking at the books and as it appears that we will already have an arcane caster I have decided to be the party rogue. I am currently drawn towards being a Zern (MM 4 page 195) adding the template Terror Vampire (Dragon magazine issue 348 page 46) which you can read all about by following this link [url=http://chet.kindredcircle.org/pdf/DnD3.5Index-Templates.pdf]Here[/url] . Alternatly I have also been considering the Etherial Doppleganger (MM 2 page 94). I have a leaning towards the Vamperic Zern personally both because of the undead with new fun tricks and the Zern mentality...In my case I would believe that I am on my way to becoming the perfect life form that my race seeks and would adventure for money and resources to continue my experiments. Most likely I would take a variant type of rogue as opposed to the basic one from the players handbook.
