I'm now further encouraged to vote for Coldness.
A question about Coldness:
If Ody anticipated liking someone/needing a relationship with them/felt some inkling of positive emotions towards them, would Coldness allow him to act in a way designed to encourage them to reach a stage where his personality could value them/be friends with them? Like, if he met some young Sidereal and went (incredibly paraphrased) "I like you, you've got spunk." would it be IC for him to enact some plans that in the future might allow that Sidereal to ascend to the ranks of Odyssial's friends?
The problem is that Coldness Odyssial's standards would be too high.
Look at the
One Being in Existence in the original setting that he would bother giving the time of day to, someone who eventually hit Essence 9 over time, when at the time, at the height of the First Age, Ingosh Silverclaws (One of the most renowned Lunars), topped out at
Eight.
He's... Less likely to make an investment unless he's absolutely sure he can control the investment, and that it's worth his time, and Exalts are just
Too hard to predict for you to figure out if fostering a specific one over a long period of time will end up being worthwhile. Sidereals just do things too differently to him for him to adequately control their growth, so he's unlikely to spend the time and energy bothering.
Fury is still efficient, but he's actually capable of giving a shit to people outside of "Does this improve my optimization" or "Does the net utility of this relationship make it worthy of the time and energy to foster it". He doesn't
Quite become nothing but a utility driven optimization machine, though he still maximizes his utility where possible, because he's still Odyssial.
I'd say Heartlessness 5-6ish would be reasonable, especially as we can still hit "Fully optimized original setting Odyssial" even if we don't completely go all in on that, and he was pretty much the most unstoppable sonofabitch in Creation there.
He was
Also one of the poster boys for why the Usurpation was
Necessary. Because overwhelming power divorced of anything but optimization towards a goal tends to tread over a lot of things in the way.
