Sharing major arcana

You can share a major arcanum with another PC or even an NPC, as long as it makes sense to do so. In general:

• Each character must unlock the mysteries of the major arcanum on their own.
• Each character tracks their own consequences separately, which means that each of you can suffer the same consequence(s)

With that said, each major arcanum is different and there will be exceptions. Talk it over with the GM and the other players to determine what makes sense.

If you and another PC share a major arcanum over any extended period, you should probably each have your own copy of the insert to track your own progress, mysteries, and consequences. Just be clear on who is actually wielding the arcanum at any given time.
