(Finally! I was called The Kulyok!
Is Paragon-hood not far behind? )
TS and Corthala Romantique are by the same author - you probably know that already. First there was a Valygar romance for TS. Then it was edited, expanded, new talks and flirts were added(and ToB content was written later) - and it became Corthala Romantique.
It was very long ago, you understand - about six years ago. Domi(Ashara) wrote many great mods since then - IWD2 NPCs, Kivan for BG2, various BG1 NPC dialogue and romances, and even mods for NWN2. But you probably know that, too.
Anyway, I'm afraid I don't know about the mod's progress much.
As for Valygar for RE, I might write some more for him. I don't know if it happens soon, though.
