[ WP ] Time travel was finally invented in 2420 , but due to technical constraints they are limited to the early bronze age as the target . You are a homeless , jobless man at 33 , and the first human tester . All they ask is that you leave a sign in the past .

`` Are you sure you want to do this? ``, said the tall men in their labcoats, hands covering over the controls of the new machine they had built. 
 
 With a light hearted grin and chuckle, Mark replied back, 
 
 `` I've got nothing to lose `` 
 
 The men in coats began working the machine. A faint blue glow surrounded Mark as it consumed him and his backpack. 
 
 `` Remember to send us a sign'' 
 
 Was the last thing Mark heard before being hurdled through the vast sea of time itself. 
 
 Almost immediately the men in coats began looking through history books and asking archeologists and historians if there was any sign from Mark in the past. Months of studying and searching yielded no results for their signal. 
 
 
 But while they never found his sign, the team did stumble upon a curious event from the early bronze ages. A mention of someone being executed for trying to scam people out of resources. He had a stone tablet engraved with 
 
 `` I'll bet you one gold coin you read this sign''.
