ToME: the Tales of Maj'Eyal

I'm trying to get all the achievements and there's a few of the remaining ones that I'm having issues with. I'm hoping anyone will have some insight - thanks in advance.

-The Sky is Falling-
Saw a huge meteor fall from the sky.

This one I understand is related to some random event that can apparently take place in outdoor zones, but I haven't gotten it on any difficulty despite playing through the game more times I can count at this point. Is it just that rare or is there some sort of trick I can/need to use to trigger it that will work?

EDIT: Got this one the very next run after posting it, and then got it AGAIN later in the same run. What are the odds...

-Last Instant of Sanity & They Came Back for Eyal-
Sun Paladin ending achievements.

Both of these require that you go through the Charred Scar and prevent the portal from opening. For some reason, despite it working on many other runs, when I go to the Charred Scar with a Sun Paladin (which I've tried 3 times on 3 different characters now), the mages don't disappear. They just stand there while the countdown goes until it hits 0 when they leave and it says I failed to stop them. I've tried everything I can think of including walking back and forth all over the path and nearby and through the mountain pass, waiting on random tiles etc. Is it some issue with Sun Paladins?

-Mender-
Destroy the bosses of the Primal Forest without killing any uncorrupted treants

More than once I have killed all 5 of the bosses with me having Treants killed by you = 0 (when I hover over one). Do I need to prevent ANY from dying? Because that seems impossible as they die to random AOEs from the other enemies from what I can tell...Not sure if I'm messing up some other way or that is really the requirement. The wiki says: "If the player kills all five Crystallized Primal Roots without killing any uncorrupted treants, they will earn the achievement Mender". So I'm not sure


Can clarify anything if needed and thanks!

I am pretty sure both Sun Paladin achievements talk about the portal in the final fight (and not the charred scar) and you will need to have taken the "Avatar of a Distant Sun" class evolution.

This is from the wiki for the final quest

If the player was an Avatar of a Distant Sun, then the Distant Sun will reveal its true colors and try to make the player sacrifice themself by throwing themself into the Void farportal, in order to open the portal wide and make a connection so that it can bring all of its power to Eyal.

The player can accept, letting the Distant Sun burn the whole world (killing the player in the process), and earn the achievement This is how the world ends: swallowed in fire, but not in darkness.
If the Void farportal is not open, and the player has at least 55 Willpower, the player can resist for a moment.
If Aeryn is still alive, she will kill the player to stop the Distant Sun's plan, and the player will earn the achievement Last Instant of Sanity.
If Aeryn is dead, a Sher'Tul Godslayer, Caldizar, will appear in front of the player, take the Awakened Staff of Absorption from them, and attack them. The Rod of Recall is disabled at this point. With the player's mind burnt away, they will attack Caldizar, but he is invulnerable and can attack with an incredibly powerful Elemental Array Burst. When the player dies in battle, they will earn the achievement They Came Back For Eyal.


I've gotten the first one, but the other 2 require the portal not be open which means you need to do the charred scar which isn't working for some reason. It also didn't work on my latest Adventurer so maybe I'm missing some step that I've done in the past I'm not sure
