pixel_player26710321 did you follow the link I gave you? So what's the last Njord mine you completed? There's only 17 Main quests for him + the side quests in his line. You most likely either need to go to the Town or Valhalla to open anything further.
However, there's a few of his quests that get opened WITHIN his previous mine. Hence the reason I referred you to the chart.
Also, please keep in mind some of us play mostly in the Mobile app where the Main Quest & Side Quest maps are separate. So stating you've done 19 of 21 mines, means very little (to me.) Please give specific location names when posting.
