I recommend 'The Ascent of Harry, Master of Death'. In this fanfiction, Harry discovers that being the Master of Death comes with the ability to see the past, present, and future of magic.

Another one is 'Harry, Master of Death: Beyond the Veil'. Here, Harry's mastery over death allows him to enter a realm beyond the veil where lost souls are trapped.

I've read one where Harry Potter, as the master of death, uses the power of the Hallows to reverse the damage Voldemort had done over the years. He uses the Elder Wand to restore the lives of those killed by Voldemort's Death Eaters and the Resurrection Stone to bring back the spirits of the fallen to help heal the emotional wounds of the wizarding community.
I'd recommend 'The Fem Potter and the Mysterious Death Mastery'. Here, the plot takes an unexpected turn when fem Harry realizes that the power of the master of death is not just about possessing the Hallows but about understanding a hidden magic that lies within the Forbidden Forest. The story features new magical creatures and a whole new set of challenges for fem Harry, making it a very unique read.
