Does Elidibus actually think he can defeat the WoL?

I think as lahabrea I would just wait for the WoL to die of old age.
I don't see the need to rush anything, the first rejoining happened thousands of years ago, and the last only 5 years ago. Surely I could wait a 100 years for the next one, at least the pesky OP WoL wouldnt be here anymore and I would just have to be careful to crush the next one before it gets too late

Since Lahabrea was talking about laws of nature unraveling because of Hydealyn it is possible that they can no longer wait. Otherwise indeed it would be smarter to wait for WoL to die on their own.
