Sorry I wasn’t sure if Alicia had made it public yet, but today’s pod episode confirmed. She had recently mentioned Waterworld as a speculated land in one of the EU expansion plots.
If it has to go anywhere, I’d prefer Islands over EU. Maybe
@tommyhawkins can confirm or deny if that space is available. If I remember correctly, both LC and the expansion between Monsters and SNW are around the same size (~7 acres). Like Alicia mentioned though, the configuration of LC may make it difficult.
