Hajoon - Blade Master Quest Bug?

[enthra]

Okay, so I was doing a training quest (The Way of Hongmoon, I think) with Hajoon in Goldleaf Foundry and when I finished the training with him, he said "Do you hear that? Something is happening outside. Follow me!" And I followed him out of the Secret Training Room and once I got out, he completely disappeared and was nowhere to be found... I no longer have a quest with him, and of course I can't re-enter the Secret Training Room because I no longer have the quest, so now I'm super bothered by it lol. I feel like it's pretty important that I complete that quest, since it's a training quest, so if someone could help me out here I'd really really appreciate it! <3

 

P.S: For the record, I'm new to the game and haven't entirely figured it out.
