-You suggest the spirit's elemental nature makes them temperamental, but then also take their accusation of Oathbreaking at face-value in terms that we might find actually relevant. The alien thought patterns of spirits make value judgments, which whether an oath is broken often is, unreliable at times.
As in, the spirits' elemental nature makes it straightforward, and direct in its nature. It'd be impulsive, but genuine.
Oathbreaker, when offered by such an entity, is a pretty serious accusation.
-You're capitalizing "mad beast" and ascribing to the term entirely more meaning and implication than it's really valid to suggest the prince meant by it. It was an invective, an insult, etcetera, not a meaningful component of the prince's request.
Still counts to their detriment. Perhaps it'd be more persuasive if we knew the prince, but describing your opponent with an immediate, provably untrue invective would be contrary to actually getting someone on their side.
Now, not a BIG detriment, after all we ourselves called Liling a top-heavy bimbo, when she's demonstrably intelligent(if not exactly slim), but its a terrible way to get some randos to help you.
-The prince coming after us after he beats the spirit is entirely unknowable on multiple levels. He might not win. He has stated other priorities. He may never find us even if he tried to.
There was some stats analysis that says he'd win.
Granted the same analysis says he'd take forever so we'd probably never see him again.
-Suggesting that the choice to explicitly seek out information wouldn't give us any useful information is a bit silly, about as silly as assuming that helping the spirit would cause the spirit to attack us because he told us to go away. (It could happen, and it'd be hilarious, but probably not likely.)
-Glossing over the potential consequences of firmly committing to a side via combat, which yes is a more concrete commitment than coincidentally doing as the spirit requested in the pursuit of other objectives..
We have two information sources right here, which leaving means we would not take either part's information but would rather find out for ourselves. Laudable, but its basically wandering around looking for clues in an unknown space.
Anyway thats just my personal value judgment on the scenario. Its intended to be an attempt at being objective and factoring in points on both sides.
My first impulse prior to discussion and analysis was to just wander off and let them spend the next hour beating on each other.
That kind of depends on the spirit in question, honestly. Supposedly there was some pact between the Diviner and the Horned whatsit, and then their kids intermarried, leading to the Weilu as the Horned Lords. It's possible that the right actions could be viewed as a breach of that ancient accord and lead to the big guy wandering off. However, nobody actually knows what happened soooo.
Basically. Certainly it's not done LIGHTLY, but we know at least one Cyan fox whose idea of treating her descendants is "lol, whatever". Blood ties are a big deal to humans.
Spirits, particularly the Sublime Ancestors, don't necessarily care the same way.
I mean, I could think of one easy way to piss off your Sublime Ancestor: if someone cracked open the memorial of Lu the Diviner and looted their stuff that'd probably not be very kosher for the Deer to see their lover's goods misused.
