He may not be full God but Achilles is somewhat divine so I have taken the liberty that he is capable of resurrection and why not bring Patroclus back with him whilst he's at it! I will continue these star-crossed lovers tale but like an episode of The Office, there isn't essentially an order but themes so hop in and out as you like or gallop like Chiron - I miss that guy. Any who, this is based of Madeline Miller's book so all credit!
