The Chosen

We know on Scadrial there are three magic systems: allomancy for Preservation, hemulergy for Ruin, and feruchamy for the interaction between the two, what we now call Harmony. I had assumed Roshar would also have three magic systems for it's two shards (ignoring Odium who hasn't actively invested anywhere) and perhaps also leftover magic systems created by Adonalsium. The two magic systems we know of are Surgebinding and the Old Magic, and it seems like Surgebinding is of Honor and the Old Magic is of Cultivation. The first problem I have with this is the reason Surgebinding is of Honor is because it has to do with binding and oaths, the definition of Honor in the cosmere, but in reality the oaths are unnecessary for Surgebinding, as we see that Ishar forced organization on the first Radiants, creating the Knights and the oaths. (We don't actually know there were no oaths before, and there is still bonding) Also we know that some of the orders of Radiants are considered closer to Honor and some closer to Cultivation. I think it is impossible to say all the spren that can form Nahel bonds are completely splinters of Honor, as Edgedancers bond to Cultivationspren which are clearly splinters of Cultivation. That being said, I think it is safe to assume that the other orders considered closer to Cultivation are also bonding spren that are splinters of Cultivation. Therefore I think it is hard to say that Surgebinding, which is half bonding to splinters of Cultivation, is completely Honors magic system. Finally, I don't like to say that the Old Magic is of Cultivation. If we look at the model of Scadrial, allomancy and hemalurgy seem very symmetrical, using the same 16 metals and having the same sorting etc, but with the little information we have it does not seem like the Old Magic is in any way similar to Surgebinding, not having 10 kinds of anything of the sort. Also in the little we have seen it doesn't seem to have so much to do with cultivation. Based on all this, the first theory I have is that the Old Magic is actually a remnant from Adonalsium that Cultivation took over when she came, like how Honor took over the highstorms. This could also explain why it is called the Old Magic. The second theory I have, which I think I actually read somewhere, is that Surgebinding is actually a magic system that is combining Honor and Cultivation. It consists of bonding with spren and then cultivating those bonds to advance. This could be explained as the Roshar equivalent to feruchamy, the interaction between Honor and Cultivation, but there are two more systems, one completely of Honor and one completely of Cultivation (maybe the Old Magic but as I already explained I don't think so). My final theory is that really Roshar magic systems are actually completely different from on Scadrial and we don't have three for the two shards at all. This is because on Scadrial the two shards, after working together to create the planet, wanted nothing more to do with each other and ended up with separate but similar magic systems and a third that came from where they interacted, but on Roshar Honor and Cultivation actively wanted to stay together and work together so they only ended up with one combined magic system. I think the biggest problem with this theory is that Surgebinding started with Honor giving Honorblades to the Heralds as part of the Oathpact, all implying it is only of Honor, but it could be explained that Honor was just more actively involved. I am sorry for not quoting my sources, this is based on many things I have read. Also I am sorry if any or all of this has been said, I am new and have only been able to read so many threads. Since this is my first post yes I do want a cookie and no I won't give you my breath (but you should know it doesn't make sense to ask someone to blindly repeat "my life to yours, my breath become yours" because awakening needs Intent).
