Curious about the origins of the isolated chamber, and tunnel system inside of you you turn your perception towards them once more hoping to gleam some form of clue as to how either of them ended up within you in the first place. After a long time of examination and contemplation you come to a realization that the chamber, and the tunnel system are not connected to each other in the slightest or at least the creator of both was not the same being. The tunnel system is only a few hundred years old at most while the isolated chamber gives you a feeling of something ancient beyond compare, as if it and its contents had existed far before your planetary body came into existence ...
Perturbed by this thought you turn your focus to experimenting with mana, and the study of the mana gathering array left behind on your surface. Though you fail to gleam anything further from the simplistic arrays you do make some small advance in trying to cause your mana to have an elemental effect in that you realize it is impossible to turn pure mana directly into something elementally aligned, as if you're missing some form of aid that facilitates the conversion.
You briefly contemplate the idea of moving your planetary body, but quickly shrug it off due to the fact that with your current knowledge you cannot facilitate it with the mana you can contain.
Mana: 660/1000 (+50 Mana a year)
Planetary Body Info
Surface: (40 out of 360 Space used)
Mana Gathering Array Network [An interconnected system of smaller arrays consisting of ten in total that gather mana from the cosmos, and draw it into you.]
Underground:
Small Tunnel System [It seems there is a series of tunnels, and chambers spread out underneath that strange array that for the most part seem bear though some of them seem to still contain items inside of them. Several of these chambers have some form of barrier around them that prevents you from seeing inside. Sealed off from the surface.]
Isolated Chamber [A chamber that is on the opposite side of your body from the tunnel system under your mana gathering array. You are unable to see inside, but you can clearly sense an entity within it that holds a power greater than your current capabilities. The entire chamber is enveloped in a array far beyond the mana gathering array's complexity that seems to be sealing whatever is inside. This array seems almost primordial in nature.]
Mana-infused Crystals [Several small pockets underground are filled with these strange crystals that are filled to the brim with a level of Mana that could fill your somewhat limited pool in its entirety though what uses the crystals themselves could have you're entirely unsure. One of the pockets has been slightly destroyed from numerous experiments.]
Iron Ore Deposit [There is one massive deposit of iron ore buried deep within your planetary body, even though its a fairly mundane material perhaps it could be of some use to you in the future.]
Mana Iron Deposits [There are dozens of tiny deposits of iron scattered throughout your body that have seemingly attracted mana during the time it took you to form though how it differs from normal iron you're completely unsure aside from it being far more durable]
Lead Deposits [There are roughly seven small deposits of lead which seem to disperse mana on contact.]
Spells/Inherent Powers
Earth Movement - You can manipulate the rock that makes up your body though the more you move the more mana you will exhaust.
Crystal Melding - You can somewhat capably meld the mana-infused crystals into semi-detailed shapes.
Mana Lash - Compressing mana into a line you launch it at your target causing physical damage from the high speed condensed mana. The more mana poured into the attack the stronger it will be.
Manasight - Using Mana to improve your perception you can now clearly observe things that might have otherwise be hidden away underground, or such. Currently the range of this sight seems to be restricted to your surface, and within your body.
Store/Retrieve Mana - Through intense study you have determined a method through which you can store mana inside of special materials, or formations that can hold mana. You have also devised a means by which to extract mana.
Known Magical Arrays
Lesser Mana Gathering Array [Costs 15 Mana to create one, takes up 4 Space, can be connected together in a network that causes the array to be more effective. Base Mana Income is 1. Five connected Arrays increases it to 10, and potentially at ten connected arrays it increases to 50. The current limit of connected arrays is ten for your level of knowledge]
GM Note: You guys do not in fact know about the sage though his existence did lead to your creation even if by accident. Also when magesight says your range of sight is restricted to your surface, and body that is when your perception is boosted with mana meaning everything around your body after a short distance is blank, you don't have a method that allows you even to find other planetary bodies let alone observe them.
