I've got a couple that aren't precisely alternate -
Mirrim's Vigil describe's Mirrim waiting in the kitchen cavern because she's too afraid to watch Brekke try to re-impress. The other is
News From the Weyr - harper Elgion returning to Half-Circle Seahold with the news that Menolly is alive, has impressed fire-lizards and is going to the Harper Hall (this was before that alternate tune!) And then there's
Ghost in the Tunnels. I've also written some
Pern songs/poems.
