Watcher of the Fields  

This is correct the next quest (6th one) is called Karath the Forgotten. It is very tough or else bugged, as it requires you to loot a precious mineral off of wind Swept Stones in TS. I have been foraging basically constantly for over 3 weeks with no update on this quest, and no response from petition. I have looted several Palladium clusters and Rough Jasper without an update. I did read somewhere that the update is looting of a Rough Diamond, but I have no confirmation of this.

You can get 5 different quests from this centaur. He's on the west central edge of the TS map, on the south side of the shore. He's got 5 flags in a semi-circle pattern behind him. Talk to him for up to 5 quests (an offering to the Centaur gods or something like that). You need to keep talking to him to get all 5 quests. Each cons yellow to me at 21, but are pretty simple things (a lot of harvesting, killing hawks, beetles, etc) although there are a couple tougher ones. Don't know exactly how much XP you get for them. I have one completed but haven't turned it in yet.
