A lineage is not a species. It is something that happened to one.

Like Custom Lineage, a lineage assumes a character who is a Human at base. Unlike Custom Lineage, it assumes something dark or twisted befell them, or that they are corrupted, or that they were never entirely returned to what they had been. The lineage layers onto the character rather than replacing what they were, which is why these peoples are counted among those who pass for human rather than filed as separate species.

They pass badly. All three sit at the hard end of the spectrum in Passes for Human: able to be taken for human, but only barely, briefly, or at a cost. An NPC who discovers the true nature of a character carrying a lineage may become Horrified, and horror in a settlement has a way of becoming a mob.

The Three Lineages

Lineage Summary
Dhampir The half-living, carrying a hunger they did not ask for.
Hexblood Those remade by a hag’s bargain or a hag’s theft.
Reborn Those who died and returned wrong, remembering little of either state.

Mechanically these follow the rules in Van Richten’s Guide to Ravenloft. The lore layer is what this index records; the mechanics belong to the source and to whatever the DM rules at the table. Variations are settled with the DM rather than assumed.

Known Bearers in Rolara

Granny Water Mother was a Hexblood before she killed her mother, devoured her heart, and took her power over water for her own. She is the clearest illustration in Rolara of what the lineage costs and what it can be made to yield.

Two known Dhampir walk Rolara: Aswang, one of the Famous Adventurers, and the merchant Xyrdoi.

Rolara admits several other peoples defined by a thing that happened to them rather than by ancestry: the Accursed, the Arisen, the Downcast, the Dreamer, the Wulven, the Werekin, the Scourgeborne, and the thirteen Borne lineages. These are filed as species in their own right rather than as lineages under this article, because their sources treat them that way, but they answer the same question about a character and sit in the same bucket. All are indexed under Passes for Human.
