The subject of this verb is all the remaining words of the passage. What remains is, first, phobera, ‘fearsome’. We have seen how terror is a pervasive mood haunting the Oresteia. Here, what remains is immediately frightening – this passage looks forward to all those future fears for which the omen and the curse play such a part. What remains is also palinortos. Unlike the first three words of the line, this is an extremely uncommon poetic adjective (that, in fact, occurs only here in surviving Greek texts). It suggests ‘rising up back again’.
