Space Whales, or a Concise Consideration on the Migratory Means of Celestial Cetaceans

Apologies for the rush job, but it was a rush job. Now back to real life responsibilities.
Everything is there except the polish. I'd like to come back for editing/layout but currently have no ETA.
The threats in the prompts mirror real world issues facing whales today.  The journey is to be an analogue for whale migration but also do double duty for climate migration.  The increasing success die forces the other players to lend a hand showing none of us can do this on our own.
Thanks for looking.
