Also in an odd sort of way it does indeed fit with Elhoim pacifism:
They make war against oposing empires (if anyhow) not those empires populance.
That whould perhaps make it fair to further increase their war weariness but decrease the modifier for: "we yearn to join our motherland" and reduce the time of: "viva la resistance" by a turn or two (since the people there are hardly effected in their way of life so they have a bit less of a reason to be upset by the Elhoim taking charge.).
Two rather "serious" problems with that though: First a flavor one which really sounds like a hard infringement on the flair of the civ (and a very major one for balance as well): if you build another civs palace you also get their war weariness modifier so if you capture a clan or doviello city + build their palace their ferocity now springs over to the whole elhoim empire?
(let alone malakim or infernal where they can war with more or less complete impunity afterwards. Whould actually be a reason for them to encourage veil worshippers to summon Hyborem so they can capture a city from him and go all-out warmongering without any need to take care about how many people die in said war. Very odd. To say the least.)
That sounds a bit much of tolerance (taking over the other civs stance towards mourderous armed conflicts.)
The other one with the lanun palace allowing Elhoim to get very rich yields from coast / ocean / lakes. (That at least makes some sort of sense flavorwise though and might not be as big a problem as it seems. And they can't terraform / build coves)
Don't know if there is a more serious effect from palace than Lanun seefood and warlikeness.
On the other hand Grigori adventurers originating in the Elhoim Empire and the likes really sound very neat and flavorful. And whould go further to explain why Grigori and Elhoim get along rather well in Lore. (Don't they?)
Perhaps war waeariness modifiers for Elhoim / even all civs could and should be placed elswhere? Seems like this is more or less necessary by any measure with the new Elhoim.
Also Calabim cities building vampires sounds more or less fine.
Seems to me they really follow a rule of complete noninterference (with the new trait) save some core principles (like determining sanctioned state religion. And make macropolitical decisions like when to go to war and what civics to run.). So as long as the cities populance followes these guidelines the elhoim only care for the unique places / world improvements nearby and look the other way if other matters are concerned (so as to not occupy another "populances" territory.).
Also calabim behavior is very much influenced by religion run and Elhoim have a tendency to favor "good ones" (so at worst you are eaten / opressed for the greather good and at best your matters are dicussed by an strictly hierarchical / evealued by a wealth centred society. Still rather better off than in calabim-controlled territory. Somehow...
i think...)
Edit: but later than 2 posts down. So got ninjaed
: + In Elhoim Lands feasting is forbidden by the games mechanics (noncalabim nations can't have their citizens feasted by vampires.). So that is taken care of already. (Doesn't mean though that no one is "eaten" in those i imagine. Bloodpet "volounteers" and others might still get their soul robbed just not on a grand scale. And some twisted things going on in those cities breeding-pits still...)
So tolerance might be a bit of an understatement / underdescription (noninterference / loose confederation might be a bit more fitting if harder to understand from reading of the word. So i can see why tolerance was chosen.).
On the other thigs: Some nice. Some unsure about. Will wait and see.
Looks like i've been wrong on doviello getting their beef up now (thought they whould get assimilation) so those seem to have to wait a bit longer still...
