Top Ten Secret Player Bases and Strongholds

The End of Time (Divinity: Original Sin)

Early on you gain access to your homestead at The End Of Time, and like every good base it's got all your vending, crafting and storage needs (not to mention instant teleportation access). Throughout your lengthy adventure you collect star stones that unlock additional rooms. The star stones not only play a major role in the story but serve a nice gameplay purpose in opening up new high-level vendors and areas. 

And yes, its name and situation as “The End of Time” is a fun homage to Chrono Trigger.
