Lace have a good path, but irilnia have only bad path for now and the future? Anothers question is the future jump time quest. Have too much kid don't go a possibility bad end for the country because the fight for the crown? Finally if you have marriage some in the group, this affect the dialogue and the ending of member group and NPC?

Irinlia has a good path, but no scene on it yet. Both girls will get their good path CG scenes later.
A fight for the crown would require that Ryen is dead, but that is not going to happen anytime soon. ;)
I do plan different endings on your choices, including marriage.
