Can't say much about their tech.
They have electricity, but rarely use it because it can attract Spirit Storms.
They use guns. But lavun based weapons are preferable.
For environmental reasons, fossil fuels are banned. Animals and lavun powered machines are used for transport.
Flying is possible, too. Lavun flight is the way to go. But this is restricted to the Guilds.
Taking to the air in a lavun powered cloud transport is amazing.
