My character is a folk hero. My plan is already approved by my DM.
When my character was young(barely old enoigh to remember his village), his village was destroyed by forces unknown to him (Raiders, marauders or something of that like). The destruction caught the attention of a passing Dragon. The Dragon found my character. Feeling compassion for the defenseless child adopted the it.
Based on D&D canon, what type of dragon is most likely to do this? What metallic or good dragon is most likely to do this, if different?
