Sunday Neverwinter Campaign
A guild of engineers who likely used water elementals to power mechanical constructs and clock towers. After the cataclysm the towers were ruined and those who remained did not know how to create new constructs so the guild died out.
They have a crypt in Neverdeath.
There was some kind of cult that developed within the Waterclock guild. It is believed that this cult was exposed many years ago by the dwarf R.L. and that some of the members of this cult have returned to Neverwinter under the disguise of high ranking officials of Oghma’s faithful. Their purpose is still unknown, but their research into the artificial Spellplague might be the cornerstone of their plans.
