FWIW I include Two-Edge under Troll culture, as he never became socially involved with his mother's people, the Gliders.
Despite his mental issues and complete lack of morals, Trolls claim him as a great Master Craftsman.
I mentioned once that some Troll families have portraits of Winnowill and Two-Edge in their homes. They don't necessarily know Winnowill's name, or anything about her.
Winnowill is portrayed as a Troll woman, whose pointed ears indicate that she is an Elf. Baby Two-Edge is nestled lovingly in her arms.
In the same manner, European paintings of the Holy Family depict a European trio in fine contemporary clothing, rather than a first-century Jewish working class family.
Two-Edge may not have been exposed to Troll culture beyond the few years he had with his father, but he was an important influence upon Troll technology.
