I still have that race of goblins that I can present as an NPC idea. They'd very much be about using toxins, poisons, and disease in war rather than traditional methods, and be more guerrilla fighters than anything. Also, giant beetle mounts and riding wasps. I'll get to work on them.

Note: They shouldn't tread on Sigma's suggested idea much because they're not a hive mind or really that advanced; they're little dudes with spears and blowguns and poisons.
