Isaac has entered a new realm, as one of this year's batch of protectors. Coming from a more mundane reality, the young engineer has been handed abilities similar to the games that he's far too familiar with. Those in the RTS genre, with these abilities read on as he creates an army to defend the Root Realm.
The Root Realm is the origin of up to four other realms, realities with differing beliefs. Each year a group of 12, three from each realm, will be sent into the reality with a prompt and new abilities to help them in their task to take on the threats of the realm.
