Deck of Many Things

The Deck of Many Things is a powerful magical item that has passed throughout the multiverse throughout all recorded time. The deck of tarot cards sometimes contains only 13 cards total, but in some rare cases it shows up as a deck of 22. Drawing a card from this deck enacts a specific powerful boon or curse depending on which card is drawn.

Some say that the item holds a piece of the soul from an ancient god of chaos. The cards often bring doom upon any who use it, but sometimes great fortune as well. The Deck seems to appear randomly and has belonged to a great many famous people, many of which caused great shifts or disasters to befall the world.

Variations
The only known variation of this are the very powerful spells cast by the Viraji wizard-kings that seem to mimic the effects of these cards exactly. It is not known how or at what cost these spells are cast, but it likely contributed to the implosive downfall of the Viraji kingdom in ages past.
