Since you've already solved the animal troubles of Trademeet, you don't need Cernd anymore (although there is a Cernd-specific quest).

Have you talked to the genies about their embargo? They want something so that they'll end the blockade. Then go aover the druid grove and look for that person the genie wants dealt with.

There's a house in the NE corner of the druid grove map. Enter it and the sahpeshifter is there - disguised of course. Deal with her and bring an item back to the genies. They'll leave.
