Can create a plane like Serra

"Good. I will, of necessity, 'walk lightly. I had thought of creating my own plane, since such planes are always accessible across the chasm, but I would have to create a plane in which both you and I could thrive, and Serra told me that such a creation would be quite difficult to manage. Black essence, which is to say your essence, and white, which is mine, are deeply opposed to each other and virtually impossible to balance in the microcosm of a created plane. Now, I do not shirk challenges, but I must avenge my brother before I allow myself the pleasures of pure research, thus I have put creation out of my mind. I will make do with bolt-holes such as this, which I will forge and relocate as I have need of them. There is an element of proximity in the multiverse, and eventually one is within an easy 'walk of a particular plane."
