Mistborn, character Gemmel

[Dwoops he/him]

Hey, so i just finished reading the short story that brandon sanderson made about mistborn, the eleventh metal.

http://brandonsanderson.com/mistborn-the-eleventh-metal/

This sparked an interest, especially the last quote that kelsier made in it.

Quote from the story

"

The bearded man loped back to the wall and glared at the keep. Kelsier slowly reined in his anger, rubbing his chest where he’d been forced to the ground. And . . . something odd occurred to him. “How do you know what I was like in the old days, Gemmel?” Kelsier whispered. “Who are you?”

"

I was just wondering if people knew more about Gemmel and who he is/ what is his importance?

Does he have anything to do with the 17th shard? or maybe worldhopping? 

Thanks

I believe all we know is that he's spiked and mostly controlled by Ruin.

Ruin was watching Kelsier, and Ruin was speaking to Gemmel (Gemmel makes the mists try to get away from him, signifying he has a spike). I don't think there's anything more to him. Just a crazy Mistborn who spiked himself, like Zane.
