After a very long time GMing the Shadowrun role playing game in 3 out of the 4 editions of the game, I am running my fist meta-planer quest for a magical character and ordeal for initiation and for the character to gain a new magical ability, in this case the ability to mask his magical aura. The plan is to run it as a play by email as this will not involve any of the other characters.
In the Shadowrun setting there is the mundane world that everyone experiences, the astral plane, that only magicians can access for the most part, and the meta-planes that are beyond the edge of astral space, and home to very powerful and sometimes very malignant beings and forces. Venturing to the meta-planes is not something to be done lightly and is a dangerous proposition, as it can take a physical and psychological toll on the magician that is taking the journey.
The character in question is a chaos magician, who barrows aspects of all sorts of traditions as part of his path to magic, in this case whe looks to the Dragon Slayer mentor spirit for part of his magical path. His goal is to seek out the mentor spirit on the meta-planes in order to learn the talent.
