Someone has to be the mad scientist right? 

There actually plenty of things Sin can do with this power, almost anything in fact! Making glass more durable or malleable, even making it as hard as steal. (anything within the laws of physics basically) Its just a matter of unlocking it and making good use of it. I won't be nation building because of the potential for invasion (or utter destruction) but for the fun of it. And to see how powerful and how big I can make Xerxes, maybe actually do this fairly (correctly, right?) this time. (in my head) This also helps build a story, which is what this is about, right? If Sin is smited in the end as is resurrected, he will start over again. (as a god would be nice). 

Anyway, I feel that Sin got way more in the short-term with Logos then long-term with anyone else. Instead of having to kidnap and goddesses pet, he got the Stone without even asking. Just me tho. I gotta prepare for- PROJECT: Ionia.
