The Inspire hub is on the Main server
Access is from the Portal Hub inner ring.
This Hub links to Buildings and Locations that have significance due to style, scale etc.
Most of them are huge so you need to allow at least 5 minutes for the site to load when you portal in.
If you are interested in building beyond mere fuctionality then they are worth a visit.
You may also wish to visit the Graveyard
Main has many abandoned bases you can discover.
If you find one you feel is truly awesome, please let a Thane know so it can be considered for the Inspire hub and long term preservation.
