Midgardsormr and the Crystals

[Belhi]

I don't think Hoary and Coultenet do; they said they joined the Scions based on tales of the Champions heroism and felt like they should be doing more to help the realm. The only NPCs I remember having the Echo beyond Iceheart, Minfilia, and the Champion were the members of the Path of the Twelve that died either in the Calamity or when Livia stormed the Waking Sands. I thought perhaps Damielliot was an undiagnosed Echo user, but he's not around anymore and it didn't quite line up.

Technically there was also a Sahagin Elder but I'm not sure he really counts and he died too.

Actually I have a theory that the Ascians all effectively have the echo too. Particularly I think Lahabrea and Elidibus were quite likely former mortals, perhaps even Warriors of Light, who were gifted with the Echo who defected. It would make Elidibus's interest in us make sense. Minfilia and the Champion are potentially two new recruits.

He just mentions he gave it to the Little Solace Sylphs as a sign that hes there for them or something like that, and realizes you did gain their trust and could potentially keep your word

Ironic considering how badly the tempered Sylphs treat the Sylphs of Little Solace.
