Jane's heart was racing as she faced the guardian of the timestream. She knew that they had to get past her, but she had no idea how.
The guardian was tall and imposing, her eyes gleaming with a fierce intensity. She held a small device in her hand, a device that seemed to pulse with energy.
"You cannot pass," the guardian said, her voice firm. "You cannot alter the course of history."
Mark stepped forward, his eyes locked on the guardian. "We have to," he said. "We have to change the past, to prevent a disaster from occurring."
The guardian raised an eyebrow. "What disaster?" she asked.
Mark hesitated, unsure of how much to reveal. But Jane knew that they had to convince the guardian, had to make her understand the stakes.
"The disaster that will destroy the world," Jane said, her voice firm. "The disaster that will kill millions, maybe even billions."
The guardian's eyes narrowed. "I know of no such disaster," she said.
Jane's heart was racing as she realized the truth. The guardian was not aware of the future, was not aware of the danger that lay ahead.
"We have to show her," Mark said, his eyes locked on Jane. "We have to show her the truth."
Jane nodded, her heart pounding in her chest. She knew that they had to convince the guardian, had to make her understand the stakes.
As they stepped forward, the guardian raised her device, ready to strike. But Jane was quick, dodging the blast and grabbing the device from the guardian's hand.
"We mean no harm," Jane said, her voice firm. "We just need to change the past, to prevent a disaster from occurring."
The guardian's eyes narrowed, but Jane could see the doubt in her eyes. She knew that they had to convince her, had to make her understand the stakes.
