Parmandur
Book-Friend, he/him
The description in this section makes Gruumsh sound Chaotic Neutral, so good Orcs could be tied to him, and more notably Druidic Orcs (which are part of the description, and common in a lot of existing D&D worlds).The challenge with knowing how orcs will be portrayed from here on out is how closely tied they are to Gruumsh, about whom we know little at the moment. He was a more balanced figure in 4E, I believe (I noped out of that edition early on), but otherwise, he's been a figure of evil and unchecked violence.
I don't know that we're likely to get the gods in a UA, but it's valuable context that we're missing in this case.
