Custom Blood Magic: Ritual
Some chronicles allow for their players to develop customized powers for their characters. The following is a compilation of player created custom content in OWBN. At this time, custom content that is created and/or used by vampire PC's is required to be listed.
The caster consumes an industrialized variant of crystal and expends a permanent mental trait. The Atlas is sustained through their blood and enables the Atlas to function. Forging the Atlas is both a burden and a boon. Once per night, the caster may concentrate and draw upon the combined symbols in the Atlas to help them decipher that which is hidden.
The caster of this ritual can view, share and edit the Atlas in real-time. The Atlas is the culmination of symbolic, visual and geographic information that has been created by all users of the Atlas. Those of tenured rank (or House leadership positions, such as Head of House) in the chain of command can delete/edit symbols created from those below. The Atlas creates and maintains a symbolic log inside the Atlas itself denoting the user(s) who have modified it. The Atlas is linked through sympathy between the Tremere blood of the caster and those who Forged the Atlas.
Mechanics: While there is one active Tremere with this ritual cast, the Atlas is maintained. Out of character there may be a secure wiki to help emulate some of the effects (or possibly represents a teacher (possibly mentor?) for low levels of the abilities preferred by House Trismegistus).. Must be clan Tremere to cast. Information does not travel so cannot be captured en route.
