Kind of a creepy quest. And the tree puzzle was weird. I guess the ending was kinda cool, although sort of a plothole in that you should be able to teleport out normally...doesn't make sense that you'd need the siren's amulet.
Anyway, I finished the quest, but I don't get the point of the coral crossbow. I randomly picked up a royal cape and sold it for 70k, which is dumb.
The new Rimmington graphics look nice.
