The Furtherance of Unicorn Conservation and Knowledge
by Lomonaaeren
After the war, Harry determines that the only people who have never truly betrayed him or spoken against him are unicorns. However, their numbers are declining in Britain. Harry decides that he will start a movement to rescue them, using all the millions of Galleons that Sirius left him. And if he can rescue other innocent magical creatures while he’s at it? He’ll do that, too!
