Cæsar

“Pain is a part of all lives, mortal and immortal,’ said the nymph. ‘It is inescapable. We all must navigate this river to get where we want to be.’
‘Shouldn’t we aim to avoid pain?’ Will asked. ‘Or at least mitigate it?’
Nico shook his head. ‘You know it’s not that simple.’
‘Pain helps us learn,’ said Gorgyra. ‘It is unfortunate, but we rarely forget the lessons taught to us in moments of pain.”
