Grub was born to goblin parents in a large tribe. His tribe came under Demon attack and Grub received a significant head injury in defense of his compatriots. After the battle, he wandered about on his own in a state of delirium, lost and alone.
Grub in Dadun
Grub eagerly joined a caravan carrying refugees from the Maglubiyet Primacy, and shortly thereafter met the Dadun Goofed Mercenary Company as they traveled near the edge of the Parched Frontier desert.
Grub fears nothing more than being left alone again, so despite his impulse control issues, he tries hard not to dissapoint his companions.
