In the Land of the Mists, power and dread lie in the simple question "What happened to me?" The following lineages are races that characters might gain through remarkable events. These overshadow their original race, if any, becoming their new race. A character might choose a lineage during character creation, their transformation having occurred before play begins. Or, events might unfold during adventures that lead your character to replacing their race with this new lineage. Work with your DM to establish if you're amenable to such a development and how such stories unfold.
What Happened To Me?
The lineages here represent a physical and magical transformation that alters you in fundamental ways. You can still appear as you once were, but you've changed in significant ways that might overwrite your once physical or magical capabilities. A dragonborn who becomes a dhampir, for instance, loses their connection to their draconic ancestry as the deathless power of vampirism surges through them. Once able to exhale destructive energy, the dragon born now feels a powerful hunger inside, and their bite is now able to drain life. Some racial traits might remain after you gain a lineage, a possibility captured in the Ancestral Legacy trait. Keep this in mind when you explore the details of how you change after gaining a lineage subsequent to character creation.
