The Keepers Sentient Puzzel Cube Artifact  

 This is more than just an artifact. Inside this cube there are weapons for protection, there is a realm that is created entirely  Soundproof and destruction proof this is so if you're trying out things you've created you have a safe space to do so it has another realm for skirmishes so your partners and companions have a place to work out and it has a 3rd and final realm  attached to it that is for development of your shadow self it is a containment area that has one way in and one way out for each of these realms and they are contaimed can entirely within the cube! 
☆ Finally is the puzzel
 Part of it is like a puzzle there are many parts to the whole and many things that can do some of which are unique to the keep that you specifically choose. These you will discover as you work and bond with your cube.
Warping
 The artifact itself can work to and from locations all you have to do is think about it and it will go there spiritually.
Sentient and gathers knowledge
 It is sentient and will gather knowledge to teach you and that you can learn within various rooms with in the cube itself.
Sheilding
 It has various including force field Earth based and many more. It can also ward create barriers purify and protect. 
A place for when companions do not listen
 I was extremely hesitant and to put this one.  It has 3 areas that are rooms that you can put a companion when they break House Rules or violate boundaries this is an absolute last resort that is designed specifically for the keepers protection. It is always imperative that 1 work out issues with the family prior to any kind of last resort method such as this . Before using this method you should also contact the conjurer that the companion is from for asistance.
Parts of this are customized  spefically this last part and being more of an offensive protection artifact part.
