Is there any continuation after the introduction? If yes, when and how does it start?
Hopefully rehearsals, training and first performance next release. However before that I need tae rebuild the journal system to be suitable to handle fit I am going to be doing wi' ballet which I am workin' on at present. Much o' the content has been written just a matter o' plumbing it in along wi' the extra content fer Ballet Secrets much o' which was supposed to be in last release but real life interfered wi' an angry ewe. there is three new locations planned: St. Petersburg Canals, Marlilnsky Threatre (both of which are now in the new Artistic Quarter o' St Petersburgh) and a third that will be a surprise and will take a wee bit o' hunting but it will along wi' the ballet content be the start o' introducing more magical elements into the game and if ye do find the third location ye probably wish you did not.
Apart fae the letter, ballet will hae a comprehensive hints and quest guide but it should be organic how you discover content and more importantly, this will piss people off, it can not be forced because a lot of ballet will be time based both for game progression and also lore. things have to happen at specific points and if people start rushing content in future things can and will likely break around magic and ballet.
if ye want to know about ballet search this thread fer me name. ye will find a lot o' the information yer seeking and fit I am planning.
