Nikis-Knight
Deity
An earlier one. Dain doesn't know about the latest offense, as far as I can tell. Might be interesting if he found out.
Riddle: who is 1st hero in game timeline (resereach/build time) that can be promoted to "Fear" ability?
Also note that Valledia the Even released him because she had ordered him to do it (or perhaps she ordered him to use this magic again after he had been convicted of unapproved necromancy in the past. I'm not sure if the case Dain mentions is Einion's wife or an earlier one.)
Necromancy fits the Amurites very well, but only after going through the proper bureaucratic channels.
Lugus, Esus, Sucellus, Cernunnos, Nantosuelta & Sirona are the gods taken from FFH mythology.
You're leaving out two gods.
But as to answer your own question..... There's Charadon for certain, but I'm blanking on a second name.
Yeah, I think AoI came out when Sandalphon was still called "Morgoth," though.
