[@VitaVitaAR] Sure thing, I'd be happy to answer.  So for the reason he is hanging around the Iron Roses is that he was sent to observe the captain. (or something like that)  In the OOC description, you talked about how many of the nobles outside, and inside, the order want the way the captain is chosen to be changed.  I'm just spitballing here, but it could be that a faction of nobles finally pressured the king enough that he had to appear to be doing something.  An "impartial" judge like the college could have been chosen to observe the operation of the knights, and see how effectively their new commander is running it.  I am entirely open to change that reasoning, but that is what I thought of as of this moment.

As for his abilities, I was going for something akin to an elemental mage.  He is adept at most of the basic elements, but his specialty is gravity-based magic.  With magic, he is able to change the weight and mass of objects. (or something like that)  He also has the ability to see mana particles very clearly.

As for how the backstory links back to this, I was really interested in the Witch-Queen of Orodagor in the Locations section.  My basic idea is that what happened to him was that a group of cultists who dedicate themselves to the "long-dead queen" were the ones who collapsed the tunnel.  They are mostly very low-powered in magic and were able to do that by having multiple people working together.  When they realized their luck at capturing a mage Chrollo was trapped and experimented on.  The tattoos are mostly a dark language the cultist didn't understand but didn't want to risk cursing themselves with.  They managed to write down actual enchantments twice while tattooing his body by pure chance.  The first one was his eyes, which gave him the ability to see mana particles, and the second was a strengthening enchantment.  This strength enchantment allows him to survive the stress of using gravity magic.  After his eyes began to glow they realized they had accomplished something and began to scribble whatever they could find, including the elvish words Chrollo had been studying in his journal.  And then in some probably elaborate way, I don't want to waste your time with Chrollo eventually escaped.

The reason I didn't put that part in was that I had begun to get really worried that my CS was getting way too long.  Though I guess I ended up writing it all anyway so...  If you have any questions or changes pls do not hesitate to state them, I know I can be a bit difficult and tend to ramble so I am sorry. Thx
