Aetheneum Delving

[CharlesSc]

Hi,

I'm not sure what the intent of "Aetheneum Delving" is. I get it that it can be used to get a bit of useful knowledge for next event, but it also says that I might get "temporary knowledge of an ability." Does this mean that I could ask to get a one use skill that I normally wouldn't have? Also, could I try to focus the "glimpse of knowledge" on a specific topic?

Thanks.
