'What's my name? Good question, oh I have the perfect answer for him.' Were the thoughts in Calder's mind as he started to think of how he would answer the question he then answers, "My name is Nunna Beesness, I know it's a very exotic name. I am a very exotic person, you see I sell shells. That's why I am in shell town, sounds like the best place to sell some shells."
Calder pulls out a random dial and shows it to the marine in front of him then gets a bit closer then says, "See its a shell, girls love them you see. They can be made for a gift for anyone really." Calder lying through his teeth not sure what dial he grabbed he had a one in three chances of three dials between a flame, breath, or impact. The breath dial wouldn't help much, the flame dial is more ideal he could light this marine ablaze. The impact would hurt himself but would throw out any stored energy within it, if he remembered to storage energy in it.
It looks like a shell, Calder hoped that would be enough to con this Marine to drop his guard as he got closer, and as close as he could get. Should this fail to sell his story he prepared to use it. Calder giving a friendly smile trying to seem nothing more than a salesmen. Although his name he gave them might just get him in trouble if it is too looked into.
