[@Mae]Miselian appears often in the tales of heroes, so he'd be pretty well known. But as the ages pass and organised warfare becomes more of a thing, his worship mainly shifts to that of honorable warfare.(along the lines of Athena of greek mythos) Currently, his key locations are probably spots where he met, fought and battled heroes or where he left legendary weapons for heroes to find (which may or may not still be there)

Miselian also made the hall of heroes, a location in the afterlife only for the heroic. (Akin to valhalla). This is probably quite well known to people

Ylonia is probably only known as a minor deity, who played the key role in the tale of the death of a far better known elder god. I imagine her worship rises through the ages as art begins to develop. She'd be best known as a muse to artists, and that will then spread her worship as a goddess of beauty and love to the general popace. She doesnt have key locations now. But artisan guilds might be in the future.
