Grogur was a male Gamorrean guard who worked for the Hutt crime lord Jabba Desilijic Tiure during the Galactic Civil War. Sometime after the Battle of Yavin in 0 BBY he was one of the guards at Jabba's Palace on the planet Tatooine.
Behind the scenes
Grogur was one of thirteen Gamorreans that could be found in Jabba's palace in the MMORPG Star Wars Galaxies. This contradicted several other canon sources that claim only nine Gamorreans worked in the palace. This was further contradicted by the fact that Jubnuk, Thug, Thok, Warlug, Ghana Gleemort, and Grissom were not in the game, suggesting that a total of nineteen Gamorrean guards worked in Jabba's palace.
