So I got to level 80 and upon checking my mailbox I got a gift in the mail from.....wait for it.......FUCKING Rhonin.
Now up to this point we thought he died in the Tides of War book, but this apparently hints he is still out there. Boosting heros he finds worthy. Why all the secrecy? Is he building an army? Did he become infused with the bombs power?
My theory is that he was infused and given a glimpse via the blue dragons magic of the titans; and aspect's charge. Think about it, his partner in crime is killed in much the same way, I think they are being set up for a future story plot about being dragon infused to some large degree.
