The Mayan ceremonial dagger had an inscription in the ancient language that read: "Offer thy heart". It's obviously an instruction left by the past inhabitants of this forgotten place, but who would be stupid enough to stab himself in the heart with a rusty old knife found inside a tombstone? After activating my battery pack the dagger shimmers brightly in a cyan light, the creatures are coming, I can hear their steps. 'It's do or die.'
Inside the Alamo dungeon after the entity rank Bloody Mary that blocked their only path to the outside was killed, the members of the society lamented their current situation. Killing the entity rank cryptid came at a great cost and it left many people whose injuries could only be healed with serum, but it was necessary since it blocked their only path to exit the dungeon.
All the hunters that were blinded when Uriel summoned the cryptid were left helpless until they managed to buy serum, which they couldn't do because there were too many cryptids blocking their way. This forced them to send even more hunters to slay the Bloody Mary, causing more wounded and the need for even more serum.
In other words, Easton strategy to draw in as many cryptids as they could to trap the Dungeon Raiders had backfired in the most unlikely turn of events and everyone blamed for their predicament.
