basically how ever old your feel like being, dont know of any people being born on the island YET. be careful, not all of the things on the site are in the game yet.
no prob, its basically a huge cave with glass melting ovens, anvils,worship sites, rooms, and places to mine, gem grinders, depots. its basically a city, its just underground. by the way, Tialdin is the king of silverbrand.
This should answer your questions from the first post.
If you know nothing about the gods and what they represent.
Then take a look at the side Moonsilver , there is all explained. ( Better for understanding the month of the calendar )
I don't know if cave-ins would work, because most people mine in the mining fields ouside of town (unless that is meant to be underground). Maybe in the demon spider caves though...
silverbrand is dwarftown, only for dwarves unless others are invited in, and there are no dangers in there, except for the training room which i think randelf bought, but i think he changed his mind and wanted a kitchen instead?
