I was able to get Glenn, but from what I can gather, every game is different depending on what choices you make in different scenarios. For instance, I haven't been able to add Korcha to my party, but I did add his mother, Macha!
After Kid got sick, Macha took me back to Termina. I found Glenn talking to the flower seller near the main gate and he tells her that he needs to get to Dragonia Fortress but he needs a boat. Then I went down to the docks where I had Macha waiting for me with her boat and Glenn showed up and joined my party. Maybe you can catch up with this scenario.
What a great game though!! I like it! Don't know about the green dragon (yet!!)
...whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable--if anything is excellent or praiseworthy--think about such things.
Yeah mom... great game indeed... the Dragons were all designed by the same guy who directed "Escaflowne" (An anime series... now playing on Fox5) Its really cool... looks ALMOST like Vanguard Bandits... You should check it out.
The Green Dragon is at Gaea's Navel, but getting there is tough it took me forever before I finally was able to get there but I don't want to spoil it for you. If you can't figure it out I can give you a couple of hints that would put you on the right track. If you want them just email me wouldn't want spoil it for anyone who doesn't want it.
