Completing the first main quest after arriving back at Norfall and completely several side quests along with defeating the owlbears has earned the players enough experience to advance to the next level. You are now at a perfect 21,000 experience point total.
Additionally, the party has managed to come away with a large sum of gold after selling the baby owlbears. Gideon fronts the party a payment of 9,000 gp for a job well done.
Lastly, to track in-game time, five days have passed with all your traveling about. Another week and the first month will be passing.
