The dragon has fought 3 or more arisen before you... perhaps he is reminiscing the excileration in battle he felt before... The Dragon also awakens every 50 years or so after another arisen has failed to kill him(or took grigori's deal) perhaps the dragon takes a nap? The seneschal has to wait for the next generation to age enough for the trials to begin anew.(your character is at the very least 18) this implies there is a calm(kinda like final fantasy X where the land is peaceful for a while)

Mercedes and Julien also mention the dragon can attack anywhere on the globe and that their armies have sworn to aid any nearby country under attack by the dragon(though they could never win- as only an arisen can slay the beast and their homelands don't care much for gransys in the end)
