Well, actually, Aaron had noticed the stag's presence for quite some time now because, unbeknownst to everyone else at the time, the Thunderhoof had been fighting against a few of the demonic beasts on its own right after it noticed the beasts storming out of the forest to rampage in the city.
At first, Aaron had been doubtful because he didn't really see Thunderhoof fighting against the demonic beasts due to the distance between them, and the only thing he could see at the time were electrical sparks that appeared from time to time. But he had assumed that it was Thunderhoof because of how small the rampaging beasts were.
Before today, Aaron had heard about how demonic beast tides usually were.
He had heard that most demonic beast tides used to happen with at least two hundred to three hundred beasts rampaging a city.
