Soooo...are they still alive but doesn't know that Vatilius (Judas) did in fact survive on Earth?? or did they die out there thinking Vatilius had died??

eitherway, great lore expansion! I just love to see the world building around them! ^^

Oh they're still alive! They don't know that Judas is alive and Judas doesn't know about what happened to them either.
Neither one see each other again though and unfortunately Ishillian never finds out he's alive. Judas does learn that he was abandoned by them after Percedal tells him (he was made on the ship they happen to be kept on and was around them for a week before he got dropped off on earth himself)
But Judas never sees or meets another of their species again

Oohw, thats really interessting! I mean....its sad of course...really sad the longer I think of it, but also....no great story has just ''happy stuff'' happening I think ^^ Its really great to see such a deep and interessting lore, ^^
