Endings

Portals of Phereon has multiple endings, some exclusive to each character. Spoilers Below.

Evolution Default Ending

How to Obtain: Simply play through the game as Evolution. For the bonus part of this ending, you must complete the all main story event portals (archive_1 and archive_2, which requires picking knowledge at the end of archive_1) that appear in order to get the required weapons to save Siena.

On day 30 (or whenever you chose the game to end), enter the final portal and fight your way through the various battles until you hit the far right side of the map. Unlike most other event portals, you will have two boss fights at the end instead of just one: the first against Creation/Siena and the second against the Druid/Viridion. Upon fighting Siena, if you've previously picked up the cleansing staff in the earlier event portals as part of Evolution's story, you can use the staff's special ability on Siena to free her from the curse if her corruption is low enough (corruption can be lowered by fighting and destroying hives that appear in existing, non-event portals over time), which will split her off of Hebi (who will spawn nearby as a regular enemy) and cause Siena to join your team permanently. Upon completion of this battle, the Druid is next. If Siena has been recruited, it may be wise to equip her with any equipment you're carrying, as she won't survive many (if any) hits against the Druid and his minions but she does provide some useful support skills. Do note that she does not maintain any of her unique powers as an MC, as she's been severed from Creation, such as creating new units or spawning tentacles. Upon defeating the druid, Evolution is given three different options that she may pick from upon finding the mana crystal which mostly provide a flavor for the ending.

Creation Default Ending

How to Obtain: Simply play through the game as Creation.

On day 30 (or whenever you chose the game to game), enter the final portal and fight your way through the various battles until you hit the far right side of the map. Unlike most other event portals, you will have two boss fights at the end instead of just one: the first against Evolution/Nila and the second against the Druid/Viridion. Upon completion of this battle, the Druid is next. Upon defeating the druid, Creation is given a number of different options that she may pick from upon finding the mana crystal which allow her to permanently change certain rules of the game as she recreates the world. In essence, this applies modifiers to how certain things of the game function in new games you play until beating the game again as Creation (or simply reloading a save right before the final battle).

Druid Default Ending

How to Obtain: Simply play through the game as the Druid.

On day 30 (or whenever you chose the game to game), enter the final portal and fight your way through the various battles until you hit the far right side of the map. Unlike the other two main characters, Druid only has one boss fight, as he arrives after Evolution or Creation defeat the other - the loser's spirit joins with Druid to defeat the other and the winner then battles Druid. Upon defeating either Evolution or Creation, Druid is given two may pick from upon finding the mana crystal which allow him to either destroy the two gods powers (winning) or not (which does not count as winning the game).

Revolution (Alt Ending)

How to Obtain: Defeat the Overseer. Any MC works, but Druid gets extra lore.

To get this ending requires following a fairly difficult and lengthy quest. While playing as all three of the main characters, you may have come across rather vague messages that appear to be part of something greater. These three messages relate to the way to trigger the alt ending. Note: The ending does not require you actually having beaten the game with each of the three main characters nor have actually seen the messages themselves. It can be achieved through random luck, concluding the answer based on one or two of the messages, or just following an external guide.

Together, the messages tell the player that they need to enter an artifact portal on a day that is a multiple of 5 (so day 5, 10, 15, 20, 25, 30) and use a teleport stone in the first three hours of the day (0:00 to 3:00). Upon doing so, you will meet and recruit Terranva. After recruiting her, she'll request you take her to another artifact portal and explore with her. She must be in the party when exploring for the quest to continue. The next time you enter an artifact portal, hit as many event tiles as possible, as these are what progress the event. Eventually, she'll tell you she's come to understand enough about these portals and she gains the ability to create normal and unstable portals herself, for a crystal and stamina cost. However, she also has the ability to create a story-portal for a higher amount of stamina, crystals, and portal fragments (received primarily as rewards for completing portal quests). Upon creating the story portal, you must once more bring Terranva into the portal and hit as many events as you can find. Thankfully, this portal is stable, and you can revisit it as need be to complete this. This is very important, as every step will drain your mana and when out of mana, each step will permanently lower your max HP. That's not even getting into the difficult fights, such as Glow Flies, which not apply a debuff that rapidly drain your mana by -5 per turn and instead sap -5 max HP permanently per turn if out of mana., but can also replicate themselves into a swarm of annoying pests. Upon first recruiting Terranva, you gain access to a starting trait upon creating a new game that makes units immune to the mana and max hp drain effects and you can also encounter a unique mermaid, Zil, on an event tile over sludge in this world who has the trait. After visiting enough event tiles, Terranva will once again tell you she's ready for the next step and offer to build you a new portal. Be aware, upon completing this new portal, all existing portals will close and no new ones will spawn until completed. Enter the new portal and fight your way to the final boss, the Overseer and her giant pet, Horror. Upon meeting her, Terranva will begin to remember everything that happened in the past and the Overseer gives you the option of either fighting against her or simply abandoning Terranva and she'll let you go. Choose to fight and defeat the overseer to unlock this ending.

Compliance (Alt-Ending)

How to Obtain: Hand over Terranva to the Overseer

Follow the same steps as the revolution ending (see above) and then hand over Terranva instead of fighting.

Adam and Eve (Alt-Ending Extended)

How to Obtain: Follow the Terranva questline but also make sure you recruit AN_3, a unique unit found via event tiles in forests. Complete her questline, bring her into the final fight against the overseer, and then follow where she goes after the fight.
