What happens to unused Event Runes after the event ends?

[Loverboy-]

Hey everyone, I’ve been getting back into HonorBound lately and had a question about Event Runes.

What happens if you don’t use your Event Runes before the event ends? Do they get converted into something else? If so, what do they convert into, and is there a limit to the compensation? Or do they just disappear?

Just want to make sure I don’t waste anything 

Thanks in advance!
