The Cumasti per the MM?

[Havard]

I've always seen them as High Elves, while the Westryn were a mix of Grugach (Wild Elves) and Drow.

This is how I envision the two types of Elves in 3.5-era Blackmoor. Elsewhere on these forums, I've seen the suggestion that the Westryn elves were probably based on Dave Arneson's hunter elves. If so, that's an obvious correlation with wood elves or wild elves.

Good point. I'm not sure how clearly Dave defined his Hunter Elves, but he did use that term to describe some of the elves of Blackmoor; I assume the Westryn.

Reading through the d20 Dave Arneson's Blackmoor Sourcebook, I'm also getting the impression that the Westryn become more and more barbaric the farther removed they are from Blackmoor. The Westryn who live close to the Duchy of the Peaks seem to be all wolf skins, scorpion poisons etc.

I would say the Cumasti are a friendlier, open and less haughty version of high elves. The Westryn are a more xenophobic, reclusive and paranoid version of wood elves. In 5E terms, they would have the same traits and stats as their default D&D counterparts, but their lore and personalities are different. The 5E Unearthed Arcana PDF of Greyhawk's Grugarch or grey elves could be another alternative for the Westryn. https://media.wizards.com/2017/dnd/down ... braces.pdf

I think your description of the Cumasti fits very welll. I will take a look at those Grey Elves too
