The former leader of the Knuckles Clan, Grandma lead her small country down a passive path. Well-versed in her clan's legends surrounding the Chao, the Master Emerald and the Chaos Emeralds, Grandma would raise her granddaughter Tikal and pass her knowledge onto her, including an old mantra. Grandma's teachings likewise instilled strong pacifistic beliefs in Tikal who loved her grandmother dearly.
When Grandma passed away, Pachacamac took over and directed their clan into a series of violent conquests of the neighboring countries.
Unlike Pachacamac, Grandma held strong peaceful beliefs that she would instill in Tikal. She similarly lacked her successor's ambition for conquest, as the Knuckles Clan's country was much smaller during her reign.

How are you? / ... / Tikal: Huh? It's something my grandmother taught me. I never to forget it. It goes like this... "The servers are the 7 Chaos. Chaos is power... Power enriched by the heart. The controller is the one that unifies the Chaos." But I'm still not sure what it all means. But the number 7...is the same as the number of Emeralds there are. "
