Who Is Nythal? Options

I'm not sure if the question falls in this category. I dreamt I was walking through a wooded area and then two large woody arms came down from a tree and trapped me to the ground. Several stakes or large thorns also came from the tree and stabbed me in the back and I was dying. Then the tree looked at someone passing by in the distance and then it realized it was killing the wrong person. The tree's name sounded like Nythal, it was a spirit or god of some kind. It said something like 'the innocent shouldn't be forgotten' and then in compensation it revived me with extra abilities.

I’ve never heard of Nythal, doing a google search for Nythal shows that it is a common name in RPG games. Here are some similar sounding names I found looking through my sources:

Niathel (ןיחאל) - One of the names of the Schemahamphorasch associated with the last 5 degrees of Aries.

Nithogg - a dragon in Teutonic mythology who tries to injure the roots of the world tree and chews on the corpses of evil people.

Nahual (pronounced Nay-wal) – In Aztec mythology, a Nahual is your personal spirit.

In Tamil (a major language spoken in India, Sri Lanka, Malaysia, and Singapore), Neythal is an aquatic flower which denotes coastal areas and is used poetically to refer to a state of mind (loneliness and sadness).

Hope this helps.
