DnD Tiefling Headcanon
Tieflings are serial adopters
Since Tieflings really have no homeland of their own, and human mothers have a tendency to abandon baby tieflings, I feel like Tieflings tend toward the “Found Family” trope.
In the usual sense of “hey wow you guys actaully give a shit about me?? I will love you forever.”
But also in the literal sense. Random baby tiefling left alone in an alley? “GUESS I’M A MOTHER NOW.” Find a goblin infant in the caves after you’ve murdered the clan attacking that village? “Oops, congrats on your new son.”
You can’t tell me that, in a species already prone to lacking a known lineage, family units wouldn’t be like, 80% adoption.
Don’t even try to tell me that it would be odd to see a horde of babies from every race swarming around a single tiefling parent.
