So Alexis already knows there are ruins on the island? I mean, he certainly won't find Zmerr's because they're disguised. But perhaps there are other buildings scattered around on the island? Anyways. If he knows about the island, we'll have to come up with a story as to how he came to know about it. This might be the perfect chance to bring the invasion. If someone on the mainland is aware of the island and what all is on it, they could launch an attack or tell the authorities and THEY will launch the attack. What say you, Drake?
