But nobody said that he was not allowed to go. So if he didn't tell anyone nobody would find out! 

Thus after the conference ended he put on his invisibility earring, jumped over the first circle to land on the second circle table, gave the bowl of apples a good kick and raced towards the stables. 

You could be reading stolen content. Head to Royal Road for the genuine story.

He thought he heard somebody shout something involving Donny, catch and spanking, but that was probably an auditory hallucination. Due to long experience he was fairly familiar with those imaginary shouts. If said imaginary shouts got a hold of him he would certainly be in trouble, so Donny ran even faster. 

Rpg endurance was amazing, Donny decided, more than happy to have chosen a class with lots of it, though some more speed would have been helpful. Fortunately some kind Soul had left his giant eagle at the takeoff range next to the stables. Bless Cassandra for her foresight. Donny did not have to wonder who it was because Cassandra was always happy to help when it came to mischief, though sometimes she seemed to know what was going to happen before the maker of mischief even got the idea for said mischief.

Thus certain idiot took off to explore the new world without permission.
