Yod

The Spark. Smallest of the letters — a single suspended point — and every other letter begins with him (the first touch of pen to page is a Yod). He is the seed of the Name, the hand of the maker, and he is completely unbothered by his size. Contains multitudes; declines to unpack them.

Yod hardly needed to audition: he opens the Name YHVH itself. The Holy One said: you are already Mine. A point so small it cannot be divided is the only thing infinity can safely wear.
