Sirius' tattoos after Azkaban
So I've just finished juliefortune's absolutely gorgeous Memoria Incarnatum (READ THIS IF YOU HAVEN'T ALREADY) and I'm looking for other fics focusing on the significance of the tattoos etched into Sirius' skin during his time in Azkaban. Are there any recs where Sirius' tattoos are magical and significant? Any fics where Sirius explains his tattoos to Remus or how they relate to Remus would be good, too. Thanks for your help!
