I´m going for the neutral walkthrough and I just assumed a good way to do that is to take out leaders. I killed YAMA, ECHINDA, and Haniel... How bad did I eff myself here?

I can´t seem to find the cathedral and throught I could force it´s appearance by taking out the four Devas.... whoops...

I´ve looked all around for advice, but can´t seem to find it (plus cyber cafes in Esteli are slow...)

Any help would be appreciated... even if it´s just to tell me to give up and relized I cornered myself
