Grolantor is one of the third generation of giant gods, disdainfully called the "runts" by their elders - the other is Karontor. His mother is an unnamed sky goddess. He was banished to Fury's Heart by his father Annam All-Father for allying himself with treacherous Memnor, but now that Annam has retreated from the rest of the multiverse, the ban no longer applies. He now splits his time between Fury's Heart and the Abyss. The god has had to flee the wrath of his sister Hiatea on many occasions. He also has many enemies among the goblinoid and dwarven deities.
