Two new heroes have been introduced to Heroes of the Storm: King Varian Wrynn and Ragnaros, the Firelord. Both hail from Azeroth of World of Warcraft. Varian is the first hero who can change between an offense and tank class. Ragnaros can control allied or enemy forts (that have been destroyed) to access new abilities.

Varian will be included in an update to the public test realm next week, Ragnaros won't appear until December. A new map, Blackheart's Revenge will be added to Heroes of the Storm between these two new heroes.
