There are many gods in the Istarian Pantheon, but there are others who exist beyond the Pantheon... Some you know, such as Varrantoth. Others, you do not. Some are ancient and many predate members of the current Pantheon. These gods are from the Outer Realms and may not be as powerful as members of the Pantheon, such as Alyssa or Brobbet. But, they are very powerful indeed when compared to the Gifted or to the non-Gifted.
