Nobili Family
The family had Inhuman DNA, but were not aware of this until the Inhuman Outbreak. Lineage and one of his sons underwent Terrigenesis after eating contaminated fish. However, at the same time they were attacked by the rival Paguro Family, and Lineage's wife and sons were killed.
After terrisgenesis, Lineage found he could summon the spirits of his ancestors to provide advice, one of whom was the first Inhuman in the family line, Monan.
