RYU-KEN'S PROFILE

Well I loved the game but I hated the ending, it left too many questions unanswered, I hope u can answer them
1-what is the fate of the elves, did they survive baramon's attack or no ?
2-will arafell vanish after falling to the ground ?
3-are there any vampires remaining ? or Nash was the last ?
4-the whole thing with lita and adrian ?
by the way, is it getting a sequel or sth ?
