Mikawa

You speak Goblin natively (much better than one who has learned it later in life).

You automatically notice and can avoid crudely-made traps and have advantage to notice and disarm more sophisticated traps.

Change It Up! You can choose any other ancestry to be raised by instead, and exchange the known language and get 1 helpful/iconic ability those people would inculcate (e.g., Dwarves know Dwarvish and are very good with smithing or stonecraft).

Advantage on checks to know or obtain gossip for events that will soon happen or have happened less than 1 year ago.

You are haunted by voices that occasionally give you cryptic advice. The voices are sometimes VERY helpful. Other times they only want to see you suffer.

Advantage against fear.

Start with 500 extra gold, or an uncommon magical item (that your GM allows). Gain an equally powerful curse or enemy who wants it back. If you choose this background, your GM may allow you to choose another.
