Mother of All Secrets is an RPG full of occult mysteries, investigations, and intrigue. Become a young ward at an old and remote orphanage. Live your new life for fourteen days as the enigmatic masters of the House prepare you and your mates for the impending visit of the mysterious Guest.
The House's walls conceal a small world of stories, plans, and conspiracies. Every hour is fateful here. Decide where to go, what events to participate in, which goals to pursue, and who you should influence. Will you be ready to learn the ultimate truth on the last night of your stay at the House?
A Living Breathing House
Become a part of the close-knit community of the orphanage. Other wards, your teachers, caretakers, and even the family of House owners — behind every living soul, there are goals, plans, and desires. With every hour, individual plots progress, secrets unfold, and choices are made that alter the House forever.
Your Own Story
Create your own character and live out a unique story — only you decide how to spend each and every hour. Go about uncovering the asylum's secrets however you like. Make friends or enemies at your own discretion. Explore the darkest and most dangerous corners of the House. Unravel other people's schemes and draw up your own plans. Obey or risk breaking the cryptic rules that govern the orphanage and face the consequences. What will you do with your freedom of choice?
Perform actions in every scene by playing cards. These cards determine your character's skills, items, and even relationships. Different cards allow you to influence others, gain an upper hand during encounters, apply the knowledge and traits you have acquired, or push the narrative towards the desired outcome. Remember that other characters possess their own set of cards which they can play against you! Study the abilities and intentions of others before reshuffling their decks and transforming their personalities. How will you play your hand?
