Ent's Quest

[Ryastar]

In Merlassar you talk to the ancient ent guy, and he wants you to take his seeds to other islands to plant them. In the quest log, it tells you to plant one in verlon, one in vestlig, one in nordlig, and one in riftland. I was able to find the right spot in verlon almost immediately - where Regina was, however, after wandering through all of vestlig, no prompt has come up saying i found the right spot. So, i ask: does anyone know where to plant the stupid ent? I'm fed up of wandering around vestlig forever
