I am going to pick one hero that was released from the first three books of the game. It is good that they are focusing more on Book 1/Vanilla Era heroes but it would be nice if they had some variation. Most of these choices are random but they could happen.
Askr: Virion, Leif, Norne
Embla: Reinhardt, Siegbert, Hubert
Nifl: Ninian, Micaiah (OG), Mercedes
Muspell: Camilla, Loki, Keaton
Hel: Leo, Morgan (F), Tethys
Light Fairy: Nino, Maribelle, Nah
Dark Fairy: Peri, Silvia, Nagi
Nidavellir: Rebecca, L'Arachel, Valbar
