This is pretty late, but it’s better than never.
Sir Palamedes is the love rival of Tristan for the affection of Iseult. According to legends, Palamedes has a cunning and jealousy personality, and very scheming. Knowing he could never win her love, Sir Palamedes devised a plan to poison Iseult to prevent Tristan from taking his love. To end it all, Tristan had to suffer witnessing his lady died, blaming himself for her death.
Top 2 with Balin in my favorite knights. In the Eiyuu*Senki universe, Palamedes is a bit quirky, and I love this part of her. Her specialty in combat is poison that deals in current health percentage, which is great in chunking out boss with high health bars. Her affection for the MC spans from watching him and King Arthur in the act. Curiously, she poisons the MC and forces him into coitus (that’s without consent, so, don’t do it, kids). And then, love blooms from there. A very jealous love.
As the MC displays kindness and acceptance of her personality, Palamedes…falls madly for him. Considering herself his (poison) wife, she prevents anyone, except for Arthur, to be near him by her skillful use of poison. She’ll not hesitate to even kill Tristan off, and…holy shit…she would if the MC does not stop her.
