Voidborn Reliquary Key?

I found a key but where do you use it? I cant insert it into my map device. Is this a bug?

AFAIK you have to defeat The Maven to use Voidborn Reliquary Keys now.

thanks for the reply. well that is just dumb- guess i will sell it then!

I've defeated the maven, and I STILL can't use the voidborn reliquary key I have. The little symbol pulses, but I can't click it and it is like i havne't killed the maven--even though I have her voidstone.

Did you figure this out?

I had to defeat Maven AND do the Abomination map that's in that quadrant for it to let me use the key.

I found the solution. At least that's what worked for me:

1. Open the Atlas
2. Move the Voidborn Reliquary Key to the Map Device Storage
3. Now right-click the key from there and it will open the Reliquary Vault window
4. Have fun looting your shiny MB

I completed Abomination and Maven beforehand (like other comments suggested)
