What do I do with Atlas Stones?

I am following the Atlas Path and I have seen two stations. Both gave me an Atlas Stone. Are these important? Can I sell them or do I need to keep all of them for the eventual ending of the path? They are only 1 to a slot and getting more than a few will eventually cause some more inventory problems than I'd like.

Solution 1:

The Atlas Stone are used during the Atlas Path of the game.

Atlas Stone (spoilers, proceed with caution)

After getting 10 Atlas stones and going to the next Atlas Interface you can make a new star, this will take all of your Atlas stones and say that you have created a new star. Current importance of this matter is unknown and it is unknown about what the effects of these actions are.

Additional Information

Whatever you do, DO NOT SELL. A buddy of mine made that mistake early on in the game, and sold two Atlas stones. When he made it to the final Atlas location, he was unable to proceed due to only have 8/10. Afterwards he was not able to locate any more Atlas locations to gather more stones. This may be a bug in the game, but no more information at this time
