What is Aion’s Class in Rivage?
How to find the Aion flower's class
The hybrid plant Aion is one of the key story points in Rivage. To unlock the laboratory door, the password is this flower’s class. There are many red herrings in this process, but here’s how you can find Aion’s class and open the Laboratory door.
How to Find Aion’s Class
There are many misleading clues and information that can send you on a wild goose chase trying to figure out Aion’s class. The correct way to find it is by accessing the Planta Center in the Cultivation area of the Dock Station in the Kitchen.

Access Planta Center
You need a password to access the Planta Center, which can be found on the prescription notepad for Amaan in the Observatory room. The password for the Planta Center is “ORD1F”.

Identify Component Flowers
Once you log into the system, you need to choose the three plants that combine to create Aion. You can find these three plants on the file in the Observatory. Their classes are written as Begonia Rex Cultorum, Cyrtanthus Ventricosus, and Chrysanthemum Externus. Select the three plants Fire Lily, Mavors, and Escargot.

Correctly Sequence Flowers
For the next step, you need to correctly sequence their formulas in the Genetic Sequencer. Your goal is to arrange and connect the molecules in a way that retains the original shapes shown on the right side of the screen. You don’t need to repeat molecules; for example, one Fe molecule in the middle can count for all 3 plants.
If you want the exact solution, you can check the image below for the correct way to sequence and connect the plants.

Once you complete the sequencing, you will see a detailed breakdown of the Aion flower.

You can now check the output, and Aion’s class will be listed as ‘Chronoservus‘. Now you can head towards the Laboratory door and access it.
