Water (NPC)

A sapient well of water which has somehow been imbued with the power of speech can be found in Castle Britannia during Ultima IV.

Description
Shawn, a refugee of Magincia, kept a long vigil over the mysterious waters, but did not appear to know of their sentience. Should the Stranger learn from Chuckles that the water was capable of conversation, the hero would know to inquire about the altars. When asked about this topic, the well revealed that there were three altar rooms which connect the bottom levels of all eight dungeons and, that if the correct colors of stones were used at these sites, the key of three parts could be obtained.
