The State of the Voidborn

So, what do we all think the Voidborn are up to? Rek'Sai is most likely running rampant in Shurima, Vel'Koz could be going on a vaporizing rampage for knowledge but he might be smart enough to not do that, Cho'Gath could be laying low somewhere probably Icathia until the time is right to strike, and Kog'Maw is probably under Malzahar's care for the time being as he waits for "Daddy" to arrive. They may be monsters but I think their all smart enough not to go on a rampage through Runeterra cause they know there are people who can stop them.
