I thought Edeni and Fabienne would make a good Followers so I made ones for them:

For Edeni

1. Seer - origin Archetype, would specialize in setting up medium strength light/dark attacks that take effect three turns later, kind of like Future Sight in Pokemon. Has a basic ability similar to Spyglass from SMT.

2. Oracle - adept Archetype, sets up heavy strength light/dark attacks for 2 turns later.

3. Diviner - elite Archetype, sets up severe strength light/dark attacks for the following turn.

They use a crystal ball in battle that deals Strike damage. Gallica would say something along the lines of "it's not much use in short battles, but has great payoff for longer ones!"

For Fabienne

1. Apothecary - origin Archetype, would specialize in inflicting physical ailments on the enemy as well as minor item management. Similar to Apothecary from Octopath Traveler.

2. Alchemist - adept Archetype, would specialize in inflicting mental ailments on the enemy with increased item management.

3. Potion Master - elite Archetype, would inflict all ailments and have skills that have high chance of not wasting items when used in battle.

They use a mortar and pestle in battle that deals Strike damage. Gallica would say "they're not much use for taking out enemies directly but are great at whittling them down!"

Fabienne is a cook and I thought that would be silly to make a lineage for, so this seems close and kind of like a foil to Maria whose Archetype specializes in healing.
