No, you cited three reasons why the escalation was reasonable.
And I respond by showing that no, because we only knew of one reason (testing grounds) first of all, which had a climax in the battle against the attack stration in the arctic. We could have stopped there and posted spies and lookouts on the Basilisks, which had no signs of being anything more than just a front for his ordinary operations and not something that could cause harm.
But we couldn't stand Mikaboshi's presence in the city we wanted to control even for a few days and we decided to attack them, making them activate their scorched earth contingency (which we had no idea existed before) and causing the 2008 crisis a year earlier. We could have stopped there and summoned several spirits to try to reduce the damage in cyberspace or something.
But then we wanted to cause even more damage to Mikaboshi that we knew we would have to face when we started eating the other Yomi Wan for the Demon Empress throne, Lash was right in saying he is our competitor even though Molly didn't internalize it IC, and using Nora and Joe's arrest as excuse, and they were an excuse, we spent priceless favors to create a very specific superweapon and did very risky actions for a single soul we don't know or even have any relationship with. We only stopped because we were running out of energy and the troops were almost on top of us, otherwise I believe there would have been people voting to stay there.
So yes, we couldn't get out of the situation without having increased, but we continued to increase beyond the initial increase, without control, on purpose and without any influence other than the majority vote.
The arctic fight happened because we picked him out, and he was already taking his spite shot at the economy by that point. He pulled the trigger before we made any other moves. We didn't need to escalate at the end the way we did, but if we hadn't done something at that point he'd have been free to spend resources attacking it again.
All of this is secondary though, the risks we take personally and the risks we take with other people are not the same. The dive into hell was crazy risky but an unprotected mortal in the safe parts faerie is in nearly as much danger simply because they're vulnerable to everyone.
Mortals can be great and stand on their own two feet, but it's a ling trail to the top and they need to play to their strengths. That means working together, using the best tools you can get, and ruthlessly cheating as much as you have to. Never fight fair when you can put a detonate an AP mine full of your target's bane material hidden in their toilet tank.
If we're serious about this then we should have a plan and not drag him to random events
yet.
I'd suggest checking his progress and if he's ready have him do some park ranger stuff in our murder jungles. Becoming a CoD because of the wheel would be bad, but it's better than dying. We can even send ruler!Molly with him at first. He can ease his way into some exp and maybe get some pet raptors or something.
Supposing we have enough lead time I'd like that labyrinth expedition as a graduation exam. It's unknown and potentially dangerous, but inside Molly's hell she's stronger than many gods are and can do a lot to keep things manageable.
Thereafter he gets more serious work in our hell, but gets to participate in our lighter stuff out here where we can't hit an undo button on mortality.
My strong suggestion is to make him either my cheat sword build or Yog's ring design* and a squad of his own to work with to make full use of his martial arts. Maybe even pair him with Olivia as a combat buddy.
With my sword build they could work very well together, with his partially precognitive tactical support spirit helping him position everything in just the right way to clear chaff and hold down bigger threats for her to execute.
I'm not totally convinced pulling him up like this is an effective use of resources, but if we do it we should do so the right way. No IDU because it carries the risk of firebombing Daniel's relationship with Charity and Molly's with both of them. No spirit quest because he'll probably die and even if it doesn't we can't predict the side effects. Molly is the only reliable source of reasonably free power available to him, and we have to do extra work to make that happen.
*I'd quote it but I don't have a bookmark on that build. Might be good to repost if you have it handy for comparison
@Yog
You are ignoring Uriel making it work in this very quest. It has been done. In the first Age sidereals successfully prophesied solar exaltations. If you can predict who will get the exaltation, you can select who does.
Funny how the gold faction never managed to stick the landing on the exalts they wanted. Knowing one will appear somewhere isn't the same as controlling the situation.
Given everything about how they work and what they were made for I would be surprised if the exaltations didn't actively resist and punish attempts to manipulate them.
If this worked you'd need to answer why no one else ever did in a way that isn't silly or stuck appealing to a handwave of "time somehow did it for reasons". In doing so you'd undermine a significant part of their dynamic with the setting.
