This small set of Racemenu overlays includes a few words in Dovahzul and various dragon tattoos.
4k resolution, supports UNP/UUNP/BHUNP bodies for women and HIMBO for men. You can filter in Racemenu as "DB UNP" and "DB HIMBO".
CBBE/3BA bodies can probably use the back tattoos and I think the leg & forearm ones without issue.

I had the dragon skeletal wing previously in Bitchcraft, but I re-did it to remove the lil translucid bits (& also for UUNP instead now)

The words in Dovahzul include:
Dovahkiin (oh geez wonder what that means) - can be on collarbones or spine
Dovahkriid (dragonslayer) - can be on collarbones or spine
Qahnaarin (vanquisher) - can be on either forearm or right above chest, left and right

It's also got:
skeletal dragon wings of two types - on the back
dragon skull - can be on neck, chest, combination of neck and chest (a lil wonky at the seam), groin, either arm
flying dragon - either side of the waist
dragon - either thigh, either calf

When submitting images, keep it SFW

Issues:
On certain morphs - very thick bodies - the tattoos can get distorted, particularly on men.
The neck to chest set goes though the neck seam and it can look a little wonky
There may be a couple duplicate entries or mislabeled entries that got past me. If you see any let me know.
