Narygos is a usually calm and open-minded blue dragon. When Thrall came to the Nexus, Narygos announced him, but he was only given an order to kill him by Arygos. However, Kalec convinced them to let Thrall come in. It was Narygos who found Thrall after he had collapsed from the newly-chosen Aspect's back. Narygos also transported Thrall to Alexstrasza, and was among those dragons who were waiting for Alexstrasza and Thrall.
When it was discovered that the Focusing Iris had been stolen, he was the one who informed Kalecgos. Later on, after the fall of Theramore, Kalecgos returned to the Nexus and told Narygos and a few others about what had happened.
