Actually, I don't think you get essence at all. I've left it going for a while and nothing happens. You can also see that the Grotto screen just says "+0", not "+0.0000000..." like it usually does for extremely small increments. I think it does something else. My personal theory is that it increases the level of future worlds (and thus your essence rewards), but I haven't been able to confirm this. My level seemed to spike after I made a bunch, but that could happen automatically as you visit more worlds.
