What happens after Sunjiang District mission?

Seems like the servers lag a hella lately

So what happened was my cutscenes was pretty laggy (with characters flying around) and at some point it just stopped. I had to close and reopen the game client to get going again, and certainly did get the mission completed as well, but if that mission teleports me to some other place.. that I wouldn't know.

Are there any quests given at the end of that mission? Where did you end up at after that mission? Thanks.

Finishing Sunjiang District leads you to Maatu Keep, which many people already get on the way to Arborstone. Talk to Jamei at Maatu and you'll get the primary quests to enter House zu Heltzer and Cavalon, which just involve you warping to Altrumm Ruins/Zos Shivros Channel and talking to the gatekeeper.
