Seems to me we have a real scientific opportunity here. Why don't we defeat the nightmare creatures and clear the gate but then investigate the Call and go through the gate? They may be able to secure the other side and create a new human citadel. They may be able to find out more about the Call and maybe nullify it. Or... they might get trapped in another nightmare, a mature nightmare that has blossomed into a gate. What would be the consequences or rewards for completing something like that? Science has questions!!
