uhm,....

one feasible way of doing guild palletes could be adding an npc inside guild castles and making it work like Guild* Kafra Storage, that way only guilds with castles could earn* a palette, and furthermore, the variable would be something blank until said guild creates it?

the one about yuno invasion, a GM tried it before once, many complaints came in from people changing into Sage, yuno being a TP-disabled town, monster invasion would get out of hand unless strictly kept to a timeline, and then cleaned up.

and about opening new castles, I've been pushing this topic a long time xD but with what i said above, it could possibly affect if more castles are opened.
