Looks like besides the obvious ones such as recruiting Selen and Namna as well as the duration of trading rumours, the influence of seasons on the game's optional events are far more than I initially thought. Since I'm past the following possibly season-dependent events, perhaps you guys can help me verify if they are influenced by seasons or otherwise.
(On that note, the in-game names of the seasons are Sprout, Bud and Flower and changes every 30-days in the same order. They are represented by the top-left icon on your top screen.)
Recruitment Events - Selen's appearance at the HQ front entrance. Confirmed: Flower - Namna's visiting the Porpos-kin's room on 3rd Floor Residence of HQ. Confirmed: Sprout, Bud - Luvais' HQ event - Zenoa's HQ event - The stew tasting event in Tehah inn. Possibly Sprout? - Asad leaving to rescue Nakil - Asad returning with Nakil - Meeting with Hafin in Mislato River
Others - Trading rumours last for the same season they are activated...
It'd be great if you could simply note the season during which you activated any of the above events in your game.
my findings. Put asad in party. (you cant access he's mark of star page yet) I went to HQ.It was 29 Sprout season. Triggered the event he went to rescue nakil. Asad leave for a while. I went entering HQ again during Bud Season. No event. Come flower season i entered HQ again.Asad's back with Nakil. Specifics?i dont know, we can only assume Asad leave for Nakil during sprout season and come back during flower season.
after recruiting Icas, i did some trading and stopped by HQ to check on things. the Assassin showed up to check up on Icas.. it was Bud season. this may have been the first time i re-entered HQ after recruiting him, so either he shows up on your first visit back to HQ or it could be triggered by season.. what do you think?
Regarding the Asad and Nakil event, I don't really remember what season it was...but I do know it took quite a while for them to return really...made me wonder if it was completely random. Next time I'll have to keep track of what day it is.
