Deceiving Appearances

The old female, Roberta sat by the fireplace with a fire roaring away bringing warmth in the room, from the cave dwelling she was in.
She sat in an armchair patiently waiting while glancing at the video screened window that showed the setting sun over fire eaten ground. She heard noises of people coming into the room from eating dinner chattering away.
She eyed her grandchildren who sat next to the fireplace. Their chatter talk, she overheard, talking about wanting to see the surface, living above ground, before the disaster of a fire destroyed everything, causing them to live underground, including in the seas on the bottom depths via caves and underwater domes, found and created by God's Seer, Nikolas himself.
Roberta frowned sitting hearing the grandchildren's talk till they became silent and saw them gazing at the fire. She figured that they were daydreaming again.
She spoke loudly "Grandchildren, I have a story to tell you so do you care to listen to it?"
Roberta eyed the grandchildren who shifted attention from the fireplace towards her. They gave her head bobs in the ancient Human style while focused onto her attentively. Roberta began her tale.
