So your suggesting he remains mortal for long duration of the game and accomplish his goal before becoming exalted later than most? Well, it can be possible he accomplishes his motivation (to gain unsurpassed genius status as mortal) by single recognized deed and it then strikes him with solar exaltation as twilight caste. So he is not merely randomly chosen; but rather chosen because of his genius nature (which may had been destined long to come). Becoming exalted merely removes mortal limitations and he retains genius title. So he gains new motivation upon exaltation then as seeking genius title no longer is his goal.<br/><br/>Of course this asks cooperation by ST to define what the event will be like, it must be something what he discovers and realizes without needing actual rolls but rather use of imagination and applying existing knowledge to create a new invention/effect which was not discovered in height of first age. A some invention which would had earned praise of elder solar twilights in first age.<br/><br/>Of course present stage Khrui may have dozens inventions which mimic wonders of lost age (some without essence) but they are not perfect nor groundbreaking in impact as magic is always better most cases.
