Revelry Row is quite literally the "party island" of Lost Ark, and is apparently called Shangra-La by the kids that stay and party there. It's full of the same couple of NPCs dancing unendingly as if this was some sort of purgatory. And, while the island does have a fair amount of quests, a good number of useful rewards, and even its own dedicated Una's Task, there are only two Seeds to find on this Island. While it would be hilarious if those highly sought-after Mokoko seeds were behind the DJ booth or in the middle of the dance floor, they're a bit more boorishly hidden in the bushes at the edges of the island.
