Both of these responses are incorrect.

The special Wyvern that normally spawns at the Bluemoon tower in the postgame does indeed take 21 game days to respawn. It is not the same Wyvern that spawns on the road leading to Gransys from Cassardis, and the elusive, glitchy one on Conquest road.

There is a postgame BBI noticeboard quest that will cause a Thunderwyvern to spawn at the Bluemoon tower, once.  When that quest completes, the Thunderwyvern will not appear again at the Bluemoon Tower until the next playthrough when the Arisen accepts the appropriate BBI Noticeboard quest.
