Twinborn People

[Themasterhunter]

Hello. First question on this site. Sorry if its terrible. I am happy to receive advice. Also, I am nowhere near as dedicated to some of the more hardcore users. 

The spoiler is for The Alloy of the Law Trilogy.

Twinborns. does this term refer to anyone with feruchemal and allomantic abilities? I know that was a stupid question, but i want to know from you guys. Would the Lord Ruler be considered a twinborn?

 

Also, can I get some input on how the "compounding" with twinborns works? Does it function both ways? I know that miles hundreslives can compound with bloodmaking, but what theoretically, would happen if he burned gold not invested by feruchemy, and if he burned fully invested gold. how would that work, and what would the temporal and spiritual consequences be if he touched his own gold shadow?

Be complicated if you have to with the explanations. I will understand most of it. at least briefly.

Yeah, you'd eventually run into some hard limits with Steelrunning per Word of Brandon but if you had enough F-Gold to at least reduce the damage you do to your body from friction you could probably exceed the 'normal' limitations of F-Steel so long as your health reserves lasted. Though you don't really need to go that extreme to be ridiculously fast, as we saw with the Bands of Mourning letting the user move so fast as to leave a vacuum in their wake.
