   Summary

   Thousands of years at Death's side, have grown repetitive and boring. Harry James Potter did not do boring.

   So, of course, when some minor Pantheon beseeches the help of the Prime Entities, including Death, Harry jumps at the chance to stretch his legs away from Death.

   And he does so as Viserys Targaryen, The Weak King.

   The Valyrian Pantheon might regret asking for help, but Harry would make sure Westeros and beyond would know the power of dragons with Fire and Blood.
