Have we met before? (Patreon)

During our last session, Diego had a very weird encounter with a NPC. She's also a tiefling, older than he is, and they crossed by accident but she approached him asking 'Have we met before?' and after some words she said she was probably wrong, and left.

We've been wondering who she is, and we have no more clues about it. But she's definitely related with Diego's backstory, so we'll finally have more info about Diego's biological family maybe??? Very excited about it!
