The current King of the Thundering Mountains. Their previous King passed away and they opted for Obsidian to take over since he was well-respected, despite not being the biological father of anyone in the mountains. Sadly, old age is really beginning to catch up with him and he's desperate to hand over power to the rightful heir to the throne: his adoptive grandchild, Diamond. Diamond, however, is reluctant to entertain any suggestions that their grandfather will not be around for much longer and often puts the conversation off, to his chagrin.
