It probably has it somewhere on the wiki, but I'll sum it up for you:

Kragnarec used his tools to mess with the Heart of Lorkhan,and someone (was it Azura?) made them disappear. If you want more details, it is probably in the Dwemer article and the Heart of Lorkhan article.

Thats what you think but to me it will always remain a mystery (mainly because I like it that way). But...it's not a mystery. It was confirmed in the third game of the series, that wasn't my theory.
