Succession
Sometimes a Teacher wants someone to take their place, in which case they choose a mortal to be their successor. It is a long process that renders the Teacher vulnerable to death until the training of the successor is finished. When the process is complete, the original Teacher eventually fades, and the successor becomes the concept's main Teacher.
There are a few select cases wherein succession takes place involuntarily, such as for Technology.
Pacting
A process wherein a Teacher takes a mortal and shares their power. The duration of the pact varies. Abilities also vary according to Teacher and extent of powers depend on the pacted mortal's constitition. Changes to the mortal's physical body often occur with markings appearing.
