I saw an intro video the first time I started the game up. It displayed automatically, for me.
I remember seeing a button on the log in window where it displays the patch notes that lets you see the video, too.
Also, the frogloks did drive the trolls out of grobb, that happened in EQ1. However, some time within the 500 years between EQ1 and EQ2 the Gods all went nutso and war broke out (short version, see intro video). During that war, the frogloks were driven into Guk (not Gukta, which was Grobb, but Guk/LGuk from EQ1). It doesn't mention the frogloks again after that, so I'm assuming they are still hiding out in Guk, waiting to be unearthed/rescued until they tell us otherwise. They may be trying to valiantly fight their way out this very moment...
