Well, my character would have avoided anything to do with royalty and nobility like the plague, not to mention I doubt he would even be worth their time. So I doubt my character would be a good fit. However, I think it reasonable that he could know the following.

Possible long-time friends: (Most of them would have had to know him before their rise to glory, the sole exception being Elena, since they are most likely no longer in proximity and social groups that would encounter him often.)
-Kate [@RyderTheWriter]
-Elena [@SlashInfinite]
-Astran [@Thinslayer]

Possible school friends:
-Elena [@SlashInfinite]
-Adair [@Dusksong]

Aquaintances:
-Blont [@TimeMasterX]
And of course any of the others on this list.

Other than that, I cannot think of a reason Trent would know the others, though I am not opposed to the possibility. I would fill the role and, in fact wrote a scene up, but it really kept turning into "why the heck is a law abiding non-rebel, nobody from nowhere in the King's prison?"

I can write something up about the tyranny, and not needing any excuse to be rounded up, but I honestly think this jailbird would be better suited for another one of you guys.
