Modern quotative adverb with the same meaning but neutral register; のたまわく is its archaic, honorific counterpart.
Derived from the classical respectful verb 宣ふ (のたまう) meaning 'to say' (honorific), combined with the archaic quotative suffix く. The form のたまわく is the 未然形 (irrealis) of のたまう plus く, functioning as an adverbial phrase.
