War in Heaven -- Never happens.

[Fried Noodles]

I'm on my 6th game of Stellaris now. Each game since my first, I've spawned the max number of FEs the game will allow me to try to trigger this crisis. I've also stopped allowing Marauders to spawn, in case their event overrules the FE's event or something.

And the last two games I've played have been in 1000-sized galaxies with 5x Fallen Empires.

I'm not really enjoying the 1000-sized galaxies as they start to slow my game down around 2300.

My current game has two pairs of opposite FEs: Xenophiles and Xenophobes, and Materialists and Spiritualists.

The Spiritualists went to war with a Federation consisting of half the galaxy around 2377 (on Grand Admiral -- Every single empire has a higher score than the five FEs). They went to war WITHOUT awakening. Their war goal was to try to force AI to become outlawed.

Now they're toast and I claimed their capital system in order to hopefully inspire the other FEs to awaken due to an upstart overpowering a FE.

The Militant Isolationists eventually went to war with the OTHER Federation. Again, without bothering to awaken first. They probably won't last much longer. I don't know.

All that's left are the Materialists, who only just recently awakened. And the Xenophiles. (And the Ancient Caretakers, but they're just gonna sit there).

What do I do?

I just want to finish these last few achievements. :p

It's chance based by default. You can however trigger it with console commands, though I don't know what the event code is for it. (you can find it in one of the files in the "events" folder of the main stellaris directory. It should be something like "fallenempireawakeningevents")

There is a mod for that I use. Just search 100% War in Heaven, you can also modify the event in your Stellaris events folder

of course if you are achievment hunting, that helps not.

Just try 600 star galaxies with max FE and other AI and pray ;) Or look here if there is some tip for your missing ones.

Never seen it even once, I also never see any crisis except Contigency as well.

The War in Heaven will never happen without the Leviathans DLC.

Not true, the event of FE awakenings was independent of the Leviathans DLC and was part of the base game itself.

[SumYungGuy]

NOT = { has_global_flag = sleepers_awake_happened }
NOT = { has_global_flag = guardians_of_the_galaxy_happened }
end_game_years_passed >= 0
NOT = { has_ethic = ethic_gestalt_consciousness }
is_at_war = no
fleet_power > 40000
any_country = {
is_country_type = default
OR = {
fleet_power > 50000
any_owned_planet = { has_planet_flag = fallen_empire_world }

All of the above must be true. Except the OR bit. Only one of those must be true.

So, this tells us that for a fallen empire to awaken, no other empires must have awakened.
Next, it says you can't have a Guardians of the Galaxy event trigger during a crisis.
The year has to be at least 1 AFTER the 'end game' year defined at the start of the game.

NOT = { has_ethic = ethic_gestalt_consciousness } means that the machine fallen empire can not awaken.

is_at_war says the fallen empire must not be currently engaged in a war in order to awaken.

fleet_power says how much fleet power the FE must have. Meaning one that has had its fleets destroyed will probably never awaken.

any_country is_country_type default means there must be a normal non FE nation somewhere that has either (OR) more than 50k fleet power/have captured a fallen empire planet.

Key issues here are that by the time the default end game year of 2400 has passed, most empires will have COMPLETELY outstripped fallen empires in tech and power, and any end game crisis can completely prevent a awakened empire.

It's worth noting that there is one exception to this:

has_country_flag = holy_world_killed

It seems that if you demolish a spiritualist FE's holy worlds then they will spring to life without any of the other checks being met. But I still haven't read all the code here, so I don't know how that will go.

Next up we have:

mean_time_to_happen = {
years = 50

this means that on average it takes a fallen empire 50 years to wake up (AFTER all conditions have been met) This is, of course, completely unlikely. Now we are in the area of 2450, and expecting a fallen empire to still be a threat that late in the game is bonkers.

Luckily, there are some modifiers that change the number of years it takes for an empire to awaken. Bad news is that if you have 4 fallen empires in game, it applies a 2.5 factor. (Now it's 125 years instead of 50...) There is no factor for if there are 5 FEs, proving that Paradox hasn't come back to really figure out their own code since this was written. Which means that fallen empires wake up faster if there are 5 FEs, Slower if there are 4 FEs, then faster again if there are 3 (but not as fast as if there are 5).

But I digress. The important factor worth noting here is: Factor = 0.1 if any normal empire owns a fallen empire planet. Which means mean time to happen goes down to 5 years instead of 50, or 12.5 instead of 125 if you have eliminated one of the five FEs in your game.

Now, this only makes ONE fallen empire awaken. Moving down the event code...

if = {
limit = { host_has_dlc = "Leviathans Story Pack" }
random_list = {
40 = { # War in Heaven with Fallen Empire of opposing ethos
A WHOLE MESS OF CODE HERE
20 = { # War in Heaven with Fallen Empire of different ethos
A BUNCH MORE CODE
40 = { } # No War in Heaven

Now, in order for a war in heaven to trigger, you need to own the Leviathans Story Pack DLC. Then, there is a 60 (40 opposing ethos, + 20 different ethos) out of 100 (40+20+40) chance that it will actually trigger the second empire to awaken and start a war in heaven.

Also, in the code for triggering the war in heaven, you get this:

set_timed_country_flag = { flag = timed_ancient_rival days = 3650 }

Which if I've read correctly makes it take ten more years before the second empire awakens. (If you're tracking dates, that puts us at year 2536 on average if you have 4 fallen empires.)

In all, it's going to be EXTREMELY difficult to actually see a war in heaven start in the current state of the game. Good luck getting achievements.

If you don't care about achievements, you could just go into the console and type

event fallen_empires_awakening.1

Which should force the first awakening event to trigger instantly. Though it would still guarantee the war in heaven to begin. (60% chance, ten years down the line. Also, I don't know how this would interact with events deeper in the tree.)

Personally, I'd just go into the event file and rip out most of the requirements so that it happens faster. But both of those options disables achievements.

Cracking a Holy World is pretty great. It forces the awakening each time.

I cracked one world and forced the Spiritualists to awaken, then beat them into a Status Quo.

They declared war on another FE and vassalized them, causing the second FE to embrace Spiritualism.

I cracked a second Holy World and the newly-Spiritualist FE vassal also awakened in response and declared war on me.

Fallen empires can awaken without DLC, but Leviathans is required for a second empire to awaken and trigger the war in heaven.
