"By flooding with appropriate Elemental Energy."
D's answer made Lee turn around, and nod after a second, in comprehension. The sovereign added-
"When a lesser wyvern comes across an area with suitable elemental presence, like a volcano for lesser fire wyverns or a chilling mountain peak for lesser ice wyverns, they find a suitable place where they are not inured, but can absorb a massive quantities of the elemental energy. After continuing this process for years, the elemental assimilation comes to an end, and the beast wakes up as a greater wyvern.
The beast must also be very careful. In this time period, it can only open and close its eyes, and that is the only movement it could do. It is literally equal to a helpless infant. A wyvern can only go through this process once in its lifetime, so it must be careful and prepared when choosing the location.
