Entesa - Floating Arcane Island

You are a Mage residing in a pocket dimension created through powerful Arcane Magick. This pocket dimension is essentially a floating island in the ether of a small pocket dimension. It has a breathable atmosphere and contains all the elements required for basic life to thrive, albeit on this limited island. This place was created as a haven for powerful magic users seeking solace, refuse and as a safe space for study, research and further magical advancement. It was created when the maker's original world became chaotic, war torn and almost uninhabitable due to violence, famine and disease. It has evolved as a destination for magickal knowledge and to home the truly gifted and powerful among magick users from many worlds. It can only be accessed by those invited and cannot be seen or traveled to by others. The main purpose has evolved to also being a repository of a vast collection of magical tomes and arcane knowledge. It's inhabitants travel various planes and worlds searching for new knowledge, magick's and ways to enhance the power of those that reside there. They call the floating island Entesa.
