To avoid being disturbed by the omnipresent demons in Pazuniya, Leon found a rocky mountain without any Flo Demons inhabiting it, dug a hole, and hid inside.
This reminded him of his life as a baby dragon, and he suddenly thought about digging a network of tunnels on the Volcanic Island when he returned... Salovis's lair was built inside a cave, so he could just visit her lair instead of going through all that trouble.
Leon now had an exceptional memory. Before traversing, he couldn't memorize a hundred English words after a whole day's effort and often forgot them all by the next day. Now, he could memorize things flawlessly after just one look. What remained was the practice of actual application, which required constant communication to improve—mastering spoken language wasn't something that could be achieved by merely reading books.
In any case, Leon now could listen, speak, and write in Abyss Language, ready to go out and explore.
