We're going to refrain from posting a lot of pre-Beta content as this event is changing a lot in the development process.
As of right now it is a reveal tile event mechanic.
The governor's villa is getting another upgrade and it appears to be an ascended level for 30 days. Just what everyone was asking for, more ascended buildings.
The main and secondary buildings at this time will make their own silver and gold upgrades but the secondary buildings have changed again in the last week. So we won't post about this event again until it's closer to release on Beta.
