So, I would propose the following:
- 1. The free site advance that all characters (including dragons) start with counts as their first session (meaning that they will start with one Hindrance to correspond with that first session). The Dragon's Background should explain what events influenced the development of their initial Hindrance.
- 2. Following the dragon's first session (i.e., first quarter of play), the character may take all of its remaining Hindrances and spend the corresponding points immediately.
For the avoidance of any doubt: Edges purchased with Hindrance points using the above method would NOT qualify for the Born a Hero Setting Rule, as they would technically be taken following character creation.
