Character Name
Efnisien
Efnisien Efnisien is the name of the necessary chaos-bringer — a character whose capacity for destruction is real and terrible, yet whose story does not end in simple villainy. The mythology gives the name to characters who are profoundly difficult to contain within normal social structures, whose internal discord erupts outward with devastating consequences. The redemptive arc makes it suitable for antiheroes who find meaning only in the most extreme self-abnegation.

In Welsh mythology, Bran the Blessed (Bendigeidfran) is a giant king of Britain who possesses a magical cauldron capable of restoring the dead to life. In Irish mythology, Bran mac Febail is the hero of an early voyage tale, sailing to the otherworldly islands of the west. The raven was a bird of prophecy and the battlefield in Celtic tradition.”

The name projects a brooding, intense quality.”
Gwydion

Tegwen
“Compound Welsh name from "teg" (fair, beautiful) and "gwen" (white, fair, blessed). The combination creates a double emphasis on radiant beauty and purity. The name belongs to the tradition of Welsh compound feminine names and carries the same root as names like Gwenllian and Branwen, placing it firmly in the medieval Welsh naming tradition.”

“Welsh form of the Late Latin "Ambrosius", from the Greek "ambrosios" meaning "immortal" or "divine", from "ambrotos" (immortal).

The name carries associations with prophecy, hidden knowledge, and sacred power.”
Gwenhwyfar
“The original Welsh form of Guinevere, from the Welsh elements "gwen" (white, fair, blessed) and "hwyfar" (smooth, phantom, spirit), meaning "white spirit" or "fair phantom". Gwenhwyfar is the figure in the earliest Welsh tradition who becomes Guinevere in French and English Arthurian romance. The Welsh form retains a supernatural quality — the fair phantom queen — that the Anglicised forms lose.”
