Dís
Tutelary female spirit
Dís (plural dísir) — tutelary female spirits, often ancestral and often acting as fate-figures alongside the Norns. The dísablót, a winter sacrifice to the dísir, is attested in early sources. Placed at the opposing shoulder to the fylgja, marking its similar external-yet-bound status. Whether to classify dís as part of the personal soul or as a separate companion-class is a real philological question; included here in the broader sense.

Heimskringla — Ynglinga saga (primary_canonical)
Ynglinga saga ch. 33 records King Adils attending a Disa sacrifice at Uppsala. This is evidence for the public cult of dísir, not proof that a dís is an individual's internal soul component; the shoulder placement is a comparative rendering choice.
