   – Today’s agenda is pocket dimension storage, – Maks announced, telling M’Ria about another aspect of magic. – Or “inventory”, how I call it. You’ve already seen how I use it. Let’s return to the basics: pocket dimension storage is magical construct, creating a “fold” of space-time that attached to some item, like ring, bag or backpack, or to your soul. Mine is the last one, – he continued his lecture to M’Ria, who sat on the chair at the table and listened to him.
   – Space-time is not smooth and plain as it looks, – Maks created an illusion above his palm, showing M’Ria a planet with schematic illustration of how space warped around it. – Every object that has mass warps space-time around it: the more mass, the more warp. Even gravity itself is the result of space-time deformation. Also magic and exotic materials – such as element zero – are able to warp reality.
   The illusion shifted, now showing a square-ruled translucent sphere. One small area if the sphere stuck out like a bubble on thin leg, like a mushroom stipe, creating a smaller sphere.
   – This is how pocket dimension works, – he explained. – Some piece of space folds and deforms, creating a “pocket” behind ordinary space, as the result of a magical construct or anomaly. As I said, in case of pocket dimension, the “stipe” is attached to a real object. The size of pocket varies from some cubic centimeters to several kilometers and more, but last for either godlings or space anomalies. Mine is around twenty cubic meters.
   – I see... – M’Ria mused thoughtfully. Through months, her education was boosted by their soul link, allowing them to share thoughts, emotions, knowledge and skills. Not direct “copy-paste”, but increasing education the speed drastically. Some skills they didn’t share yet still “diffused” through, like intuitive understanding of working with a computer and omnitool for M’Ria or how to quickly skin fish for Maks – yeah, unfair exchange. Thus, she covered ten years of general education in barely a year, not to mention combat and magic skills.
   – But, didn’t you say that it’s too soon for me to master dimensional magic? – M’Ria asked, tilting her head. – Yeah, I’ve reached expert level in Nirn magic schools, maybe approached the border of the master level in some, but this... – She waved uncertainly.
   – It is, not for the next few years for sure. – Maks nodded, – Though I think you’re skilled enough to use my own inventory – our soul link will help with that. Plus, it’s rather convenient. First, we should to grant you access...

   M’Ria stood in the room, clad in casual clothes. Maks attached his pocket dimension to her soul, or, more like used their soul link as access point for M’Ria.
   – Using the storage is simple – just imagine or name in your thoughts the item you want to get and use the spell, – Maks instructed, – Try to get “gold septim coin”.
   – O-okay. – M’Ria even closed her eyes to focus, murmuring “gold septim coin, gold septim coin...” Exhaled, she extended her hand, palm up, and used the spell. In dim flash of light, a gold coin appeared in her hand. – I did it! – M’Ria beamed with proud and joy, showing the coin to Maks.
   – Good job, M’Ri, – he smiled. – Now let’s try to change clothes instantly. Let’s start with rings...

   In the middle of the room, M’Ria stood under her mentor and lover’s gaze, clothed in her leather armor and holding her artifact sword.
   – Good work, – Maks praised her. – Now, try to change your armor to commando suit.
   – Sure! – feeling confident in her new abilities, M’Ria focused, now without closing her eyes, on high-tech armor. Moreover, she decided to make the task more difficult and get a pistol in her left hand also. The wave of dim purple light from her left to her right, replacing her outfit. In her left hand a mass-accelerating pistol appeared, where there had been an enchanted leather, there was an airtight combat suit now. Striking a pose mid changing, she looked at Maks with smug face.
   – Nice job indeed. You did great, – he nodded approvingly.
   – It's all because I have a great teacher, – M’Ria smiled.
