Well BD, the group has been "likely" to die throughout every single thread yet.
The quest can't be created to require "help from Agamari" unless the Agamari were contained in the quest themselves, like the dwarves frozen in stone a few threads back. There's simply no way the creators could've ensured that the Agamari would even be around. "Always in motion is the future."
If you mean something outside the quest is going to kill them, I think you're underestimating the group's survivability in these situations. Especially considering the supernatural help they've got.
Either way, the group can't be strongarmed into acting out-of-character just because "if they don't do this they will likely die". Outside knowledge of that can't affect how the group will act. You need a better reason.
