The Echo Key was created by Benjamin Locke, in June 1775. Benjamin seemed to not know what function the key would have, and described in his journal that entering the Wellhouse, he was asked who he sought. When he said Joshua's name, his soul appeared, and Benjamin fled.
The Echo Key is used to summon a tangible "echo" of a dead person to the Well House. Entering the Well House, the user is asked: "Who?". Saying the name of someone summons their soul as a tangible Echo that rises from the well.
The Echo is trapped in the Well House, as attempting to leave through the door results in the Echo fading away; the same holds true for an Echo that enters the Well House. The Echo can only leave the Wellhouse through use of the Anywhere Key, where they technically aren't walking through the Wellhouse door. Additionally, an Echo inside the Wellhouse can communicate into empty spaces that produce echoes, both literally and metaphorically, as Sam Lesser's "emptiness" is what enabled Dodge to appear to him.
Chamberlin Locke speculated that an Echo "longs for the warmth and comfort of "That Other Place", and that using the Echo Key is selfish. Ellie Whedon also believed that Echoes are at peace, and therefore struggle to understand complex human emotion.
- Joshua Locke (summoned by Benjamin Locke)
- Rendell's Mother (summoned by Rendell Locke)
- Lucas Caravaggio (Dodge) (summoned by Ellie Whedon and Tyler Locke at various points).
- Rendell Locke (summoned by Tyler Locke).
Guide to the Known Keys entry Edit
"whence I unlock'd the dore I heerd a voice that saimed to ecko from the well & is aisk'd me who I sot & I spake of my brother. No sooner had the words pass'd my lips thence he ROSE from the WELL like a spairt & yet was living flaish, alltho he had dyed in the Drowning Caves not 6 weeks beefor. He clasp'd me to his bosom & sayd why do ye look so unhappy to see me brother, but I wast in feer for my allmaighty SOUL & fled to the howse & pray'd thair to the LORD
But in that grait howse, an echo of my voice was all the reeply I receiv'd"
