I don't know if this has been discussed already. I still don't want to believe that Luc is dead. but if he really is what ever happened to the true wind rune? well I don't know if my memory is correct cause it must be 4 years since I last played suiko 3 and I'm still enjoying chapter 4. now i just learned that the only person with an s affinity to wind is Luc and next to him is the only A+our not so popular tenkai star Thomas. wow I did not know he had an A+ affinity with wind, his affinity is better than the magicians. and no one wonders? well if Iremember correctly Thomas went with Sasarai to get back the true earth. so definitely he was on the final battle. unless my memory is screwed up and I just put him there. so maybe after Luc died the true wind rune sensed Thomas. and it was thinking, hmmm... tenkai star, no true rune, A+ compatability... perfect match... so the true wind rune transfered itself to Thomas, and Thomas just didn't say anything cause for him that is not a big thing. I mean Thomas is a tenkai star so he has an IMPORTANCE not only in the game but the whole suikoden world in general... I know that there are a lot of non-tenkai that posses a true rune. but usually, true runes or it's powerful offsprings or components are attracted to tenkai stars because of the great potential lying inside of them. so the true runes uses this to its own purposes.
my second argument about the true wind:
true runes are said to be entities that have their own will. they chose the person that will suite them. but in the case of true earth and true wind they were forced to go inside luc and sasarai. it was said in the manga that sasarai was a perfect host while luc was a deformed one. now I guessed the true runes did like luc and sasarai cause they did not abandon
them. but in the events of suikoden 3. luc said even if he wants to he can't
remove the true wind from him. but he was able to take the true earth from sasarai. so that brings me back to the manga. maybe luc is a really deformed host for the rune. but then the true wind rune knows that luc wants to destroy him. but either he can't detach himself from luc or it did
want to be destroyed. or maybe it knew that luc will not succeed, so it didn't bother to leave luc.
