FYI- Kara is the dragon bard. Kara, Brimstone, Raryn, and Taegan were trapped for several days within the cancerous emptiness inside the magical gate until the dragon bard eventually figured out a way to use her magic to force the damaged enchantment to function properly. Immediately upon their arrival through the gate, the seekers were attacked by a skeletal dragon golem that had been magically animated by Sammaster for the purpose of guarding the portal. After defeating the lich’s servant, the companions realized that they had finally reached the true source of the Rage, but to enter the ruined citadel itself, they would need to find a way past Sammaster’s sentinels, a force of six Tarterian dragons.
