It was quite sometime after their battle with the manticore. Though they had traveled for quite some hours they were nowhere yet. Xavier and Caesar had been sneaking their way through their journey using concealment magic. Concealment Magic was a transformation-type stealth-type spell. It keeps the caster hidden as long as one holds their breath. The moment one stops breathing the spell is immediately inactivated.
It was quite obvious that they couldn't have kept their breaths on hold for quite some boring hours which seemed to be years, whenever they encountered a mana beast, they would conceal themselves. Though Xavier probably would not like to admit it, Caesar turned out to be a bigger help than he had thought he would turn out to be.
