I had a short discussion with OA about the Hugh's individual personalities. Might come in handy for you all, so I'll paraphrase it here.
{High Island} is laid back and calm. He's noninterventionist, but prefers to act before his siblings escalate things in their own way. Of course, that would require him noticing a problem first.
<High Clairvoyant> is both meddling and motherly. The only thing stopping her from being everyone's helicopter parent is the sheer number of people she's chosen to shepherd. She is one of the more active High, just because she likes helping people.
#High Venom# is insane. She's gone so far insane that she's come around and started approaching sanity from the other side. When she acts, she acts decisively and without regard for anyone or anything under her care.
∆High Electric∆ is a businessman and a gambler. If the Laws of Thermodynamics are a game, he's learning how to cheat. This wrestling with the basic laws of reality is why his interaction with the city is limited to providing power; it's what he does subconsciously.
~High Prescient~ is bored. Really, really, really bored. Einstein said God doesn't play dice with the universe. He was right, if only because the Prescient has designed their own game played on a level that confuses even the other High.
