I dont like the idea of players choosing the town to spawn in. Everyone would just pick aridus. (on that note: aridus should not exist in Volucris.) I think all players should spawn in Semel, and then as they journey outwards they can make any of the other towns their default spawn place. Maybe you can make it so that Players can say -markspawn to mark their spawn place. But you can only mark towns and castles/towers. (maybe something different for warlocks. They need a "lair")
The map should probably resemble Xenimus's map. But I think it should be scaled up. Big time. The oldest, original continent should take up the space of all of xen as it is. A walk from Semel to Terthius should take like 30 minutes. Other continents can stay but they should probably be devoid of towns. I like the idea of civilization being confined to one island and evil stuff everywhere else.
